mod armors and morphs

[Walikonix]

so basically my problem is that my armors scale with the body, but wont adjust when it comes to pregnancy, from fertility mod to be precise. however when i wear a vanilla armor not modified in any way, its working perfectly. so is it something i did wrong or are certain armors just not compatible with pregnancy morphs? example Remodeled Armor for CBBE Bodyslide HDT
