I just discovered there are hundreds of messages I haven't been seeing. They all have the "Inbox" label, but don't show in the inbox. They show when I search for them, or in the "All" folder (which I just turned on). I'm using folders/categories. The only messages in "Primary" are the ones with no labels. I don't know why these messing messages are getting the Inbox label.
Any ideas?
