Same happens to me on Switch. Every time I was forced to login to Microsoft account, like it wasn’t saving it. When I got my switch 2 and played in Minecraft a couple times in a realm this didn't happen, however as soon as I transferred my save data from Switch 1 it began doing it again. I can only assume this is some kind of issue with the save data but I don't want to delete my worlds.
