"some items of your backpack cannot be recognized by the system, please make sure your backpack permission is public"

Never had any problem with offering items to dispenser logistic but from now i cant send any item to it due to this problem, obv mine backpack is full public..
Any way to fix?

Readed now the sticky about CSGO items, seems the problem.

Okay, now i have this problem too on steam gift items..
