Custom Heightmap problem

Hey guys! I tried to make the heightmap for my Urbz world but it shows up flat in my world.
Here's what the actual map looks like:
And here is my heighmap for it:
Can somebody please take a look at this for me? Thanks!

If you open the height maps from CAW you can get the gray values for the heights you want. Black would be the lowest water level.
Or, did you try the 300 height/level?
I did actually pick this one from all three heights, I tried the 100, 200 and 300 shades, and neither worked. And I indeed did try the 300 height level.
I love your worlds by the way!
CAW isn't working on my laptop and I don't know why... Try lightening the gray, maybe?
Hopefully someone can look at it. Good luck!
The complete image will then be visible in your post.
You'll need to increase the contrast between lowest & highest level of hightmap.
Black being lowest & white highest.
If you make the bottom of the river very dark grey & land med/light grey.
The 200 or 300 map will probably work.
Edit: I'd consider re scaling river. It might be a bit big on a 2048 x 2048 map.
If you're planning on using a distant terrain with your world.
You'll not want to build too close to edge of map
And honestly that's what I did, I picked the greys from 100, 200 and 300s and neither worked, so I just tried white and black and it did this^
For both of you, I would pick out one of the pre-made heigh maps (the island, for example) and duplicate that image file, and open that file in whatever image editing program you are working with. Make a new layer (if you can) and make it entirely black. You can hide that new layer to go back to the island png and select shades of gray, and then go to the new layer and draw whatever you want. For the urbz map, I would just past it into this document and adjusted it to the right size, and then adjust the contrast/brightness/curves to bring the grayscale into something that looks reasonable. based on the island png. Before you do this, it might be helpful to open up the island in CAW to get a sense of what it looks like
When you are done editing your new height map and before you save, merge all your layers down (flatten the image) to a single layer. IYou can check and make sure the mode/scale of the image is what it should be, but you shouldn't have to change anything since you are just editing an image that you already know works. Save it, change the name if you want, and import this edited file back into CAW. That should work.
My issue was a bit different -- CAW was applying my custom height maps to only half of the map despite that I used one of the default templates as my base. I tinkered around and eventually got a version that applied the height map twice, side-by-side in the world. I realized that the former image had a bit depth of 32 and the latter had a bit depth of 8.
Like how the thumbnail required for your world is 16 bit depth, so is the height map. I use the free image software called GIMP, which has not had an automatic way of toggling this until recently, so I've always found this frustrating when trying to make my thumbnails (I've always had to tinker with settings until I stumble upon the right combination to end up with a 16 bit depth save file).
LUCKILY, the new GIMP 2.10 and newer (first released April 2018, latest version as of this post was released April 2019) now have a "Precision" option under the "Image" drop-down. You can pick 16-bit and it will automatically convert the file for you!
Hopefully this helps someone else having this issue and Googling for a solution

I'm having the exact same issue, except I'm using the newest version of GiMP and set the precision to 16 and it's still happening. I'm so frustrated.
