Campaign progress resets to 0 after logging back in (Online Mode)

I've been playing the campaign in online mode and was logged into my account. However, after I log out and then log back in later, my campaign progress is completely reset to 0.
Does anyone know how to fix this? Thanks.

I know my progress was saved at that time, because I took screenshots of the levels I had reached (though I don't see a way to attach images here). Is this a known bug, and is there any way to restore my progress?
