This is an unusual problem that I also witness over and over again. The unusual part is that I'll get same-source emails (eg: mailing lists that I follow) scattered between two different tabs, so it is like Google only forgets where they go sometimes. I drag them to the proper tab each time, but it doesn't seem to fix anything.
