Odd issues with pet battle team vanishing randomly

I have an odd issue where my pet battle team randomly resets. As in it just “forgets” my team. And I have to reassign them. Also if i drag a pet to my action bar. The icon will eventually become a question mark. I’m not sure if this topic belongs here. I wasn’t sure where to create it. Thank you for reading.

I know the question mark will appear if you’ve caged that pet. Even in cases where you might have 3 of the same pet, if the specific one assigned to a team is caged it won’t automatically switch to another of the 3, it will just mark it as unknown slot with a question mark. This is using the Rematch addon.

Are you using more than one account? Sometimes when I switch accounts the team on the new account gets messed up.
