MINECRAFT SKINPACKS ISSUE.

When I try to open a skin pack by pressing +, it doesn't open in the zone of "owned skins". Also, I replaced the persona file with a custom persona I had made, and I can't see it, the standart minecraft persona pack remains instead and can't even be opened neither. Anyways, the 5 slots for selected skins still have the skins from my custom persona. Although this custom persona doesn't show I can see it in the minecraft files by using iobit unlocker.
