A strange Serana's clipping issue

[ccwwdz]

I use this female outfit replacer (physics): https://www.nexusmods.com/skyrimspecialedition/mods/23003?tab=bugs&BH=3, 3BA body, XPMSE, CBPC, HDT-SMP. Everything works perfectly except one little problem.

When you stand closed to Serana, there is no problem at all. But if you make Serana wait you and you step back to get a little further from Serana, some pieces of clothes, having the same color as her cloak, around belly area will gradually get through her body and float in front of her belly/wrist. If you get closed to her again, those weird pieces of clothes gradually disappear and everything get back to normal... Did anyone experience this?? I guess it caused by the her cloak or physics or something? If I use bodyslide to make her wear vanilla outfit and there is no this problem.

I observe it more carefully. It seems that the piece of cloak near butt area use the butt's physics. And that piece of cloak will get through her body if I am far from her.
