Lately, when I'm trying to change custom skins from a skin pack, the old skins show up as Invalid, and the Delete or Edit Character buttons are in a "non-usable" state (I can't click them, they're greyed out)

This persists on Nintendo Switch, as well as iOS

Steps to Reproduce:

1. Upload a custom skin file
2. Log in on another device
3. Navigate to the slot where the custom skin would be

Expected Result
The skin should have an "Edit Character" button and a "Delete Character" button, both usable and not greyed out

Observed Result
Both "Edit Character" and "Delete Character" buttons are greyed out and cannot be clicked

If you need a visual on what I'm talking about, see attached screenshot from my phone

UPDATE
Lately this has also been applying to deleted skins as well. I delete a skin on my Switch and I can't make a new skin in that slot on my Switch
