Whenever I leave the menu of my realm it go to apply packs

When ever I go in to the menu of my realm like to invite a person or change something or looking at backups and then I hit b to go back to the main menu it would act like I added packs and apply them to the realm and it would kick everyone off that's in for no reason and sometimes it would say couldn't apply packs when I did change anything and they were already on the realm. This is really ignoring that it happens.
