Problems with addons panty!

Hello guys!
I’m always here asking you things about the bottom most hated by me personally: The underpants of the costumes; panty.
Every time I put one in, I find new problems.
I attach the screenshots to make you understand the situation.
Am I wrong to compile the YMT file? Usually I put 17 on prop mask because the model and texture finish with r and whi.
Could you give me a hand?
P.S I have a mod that improves the texture of the woman’s skin, but even removing it, the problem presents itself equally.
