layer becomes invisible after adding art mesh

I have a model i was adding Artmesh to every part using the "Auto Standard" suddenly when i got to the legs as soon as i added the mesh the "drawing" dissapeared, is like the layer is still there, but i cant see the legs its like if they were hidden for some reason, if i open the manual editing i can see the legs if i select Display: Show model image in display menu, but i cant exit manual editing via Check Mark (its greyed out) because it opens an alert window saying "Inappropriate Meshes" when i click it.

Live2D Version: 4.0.05
OS: Win10
CPU: AMD FX-6300 Six-Core
GPU: Nvidia GeForce GTX 1060
Memory: 16GB
Illustration Software: I believe it was made via Photoshop, like 80% sure

So here the pictures:

1. the first one is manual editing with the error window and i can see the legs
   
2. the second one is outside of manual editing and i cant see the legs
   
3. third one is without art mesh so i can see the legs
   

i tried it again in the third one and it does the same

Thanks in advance!
