keeps making prefabs and messing up my unity projects

hiya josh! ive recently been using your inventory inventor for about 2-3 months and never had an issue with it up until now. ive been trying to upload avatars using inventory inventor but every time i import it, it messes up the project and keeps making prefabs which is strange as its only recently been doing this. i hope to hear back from you. many thanks
