new modder pls help

hii guys I'm really new to modding and so far, everything seems alright, and I've found fixes to all my problems except one. there is a random yellow flat texture in the wild that I can't fix. the only mods related to plants I have is Skyrim Flora Overhaul SE and assorted cathedral flower mods (screenshots included in link). most of my mods I've gotten from YouTube videos, and I've done my best to make sure they're compatible before installing. If anyone has had this problem or knows what to do to help I'd be very appreciative. (beware I know almost nothing of computers and modding so bear with me if these mistakes seem stupid or if I need extra explaining)
