Cleaning "all mail" in Gmail, I noticed there was a lot of unread messages that were not in the inbox, in the trash or in some label. They're just messages that I received and had never seen... This is not the first time I think the messages are skipping the inbox, but I don't have any filter with "skip the inbox" and it's not a POP account. I'm using Priority Inbox.
What should I do to prevent this from happening?
Where go these messages?
Two screenshots: The first my inbox with no unread messages, including the labels:
The second, after an "is:unread" search. Note that before performing the search, I cleaned the spam and the trash. I just don't know where are these unread messages, once they aren't in the trash, the spam or in any labels.
