Duplicates of loyal skins

Some loyal things in the "Belongings" tab are repeated twice. I assume that this is due to klei rewards, since there was apparently a mistake due to the fact that she did not notice I already had skins. Despite the fact that I knew for sure that I already had these skins, I took them, thinking that they were missing from me. However, I got a second version of this skin instead. It turns out that in klei rewards you cannot get the same skin for the biffalo hat that we received in the year of the pig, in klei rewards you can get a copy of this skin. The stra ngest thing is that this does not work with all skins. I don't know about others, but I have copies of skins for "Carrat torch", "Pig King Hat" and "Stalked Heart"
