need help desperately, terrain broken

[PelinalWhitestrakeCrusader]

I'm trying to make a heightmap through photoshop, but when I import it in CK with tesannwyn most of the terrain results broken, screenshots:

I can't figure out why this happens because I didn't use any biggest difference in level , this is a screenshot of the heightmap in photoshop, 4096x4096 pixels and displayed in 1:1 ratio in the point where there are the biggest differences in level of my heightmap:

how you can see there aren't so big differences, when I used tesannwyn I wrote:

TESAnnwyn.exe -i Skyrim -p 1 -b 16 -d 4096x4096 -x -64 -y -64 -h -22192 -s 0.250 -w name name.raw

So I even reduced a lot the vertical scale, it should flatten the terrain and reduce differences in level, but the result is still what you can see in those two screenshots.

 

I don't know if the problem could be that I created first the heightmap within CK and then exported it into photoshop to expand it with other terrain but not modifying what I made within CK (I find it easier with CK because it has a more graduated scale but it allows only 2048x2048 heightmaps so I had to use photoshop to put more parts together). And when I tried to see the terrain after doing its heightmap within the CK before exporting it, the terrain wasn't broken.

 

Thanks to anyone who answers
