Pose icons don't show up in game

I have quite a few poses now that just show the lamma thumbnail in game instead of the one it should. I decided to take a look on those pose packs in Sims 4 studio, but everything seems normal, the thumbnails at perfectly fine. Do any of you has any ideas why is this happening or how to fix it? Can it be because I use wicked whims for posing instead of the pose player?
