11 Mesh Groups in CAS Mesh Causing Problems

I have been working on making overrides for career uniforms, and was working on the doctor one, for GTW.  I have opened a lot of meshes, and worked with multiple mesh parts, but this one has 11 mesh parts!  Normally I would delete what I don’t need and then unlink the geom info from cas part and region map, but for an override to work, I have found, one cannot do this.  It needs to have 11 mesh layers with correct cut numbers to work, or the game will put the omitted ones back when it generates the sim with the uniform.  Anyway, the issue is one mesh layer, with the cut number “000A” and I have mine matching that, that was the original I exported, but it ignores mine and puts EA’s back.  Everything else works fine.  Any ideas on how to fix this?  If I need to rework my mesh a bit to cover the problem mesh part I can, but I’d rather not.  Thanks!
