All my tasks are listed twice

[MTrainor]

No matter what view I pick, each task is listed twice. If I delete one, both
are gone and there's only one in the deleted files folder. If I restor that,
there's two back in the task folder. It doesn't prevent me from doing my
regular work and I don't have the time to figure it out on my own anyway, but
it is very irritating. Can anybody help with this?
