Hello. New user of GoodTask here. I have noticed that if I move a task from one list to another (whether to another list in the same account or to a list in another account), it becomes duplicated. If I delete one of these duplicates, the other one disappears as well. If I do not delete the duplicate (I cannot tell which one of the two is the 'duplicate') but restart the app, I have just the one task. Am I misunderstanding something here? Is there a setting I am not aware of here?
Yes, I see now that the duplication only happens when I move tasks between lists on a CalDAV account (Fastmail). In fact the duplication seems to be only temporary, as after a minute or so the dupe vanishes (perhaps after a sync).
I can confirm that, it happens to me as well on a regular Outlook.com account. It seems to be a glitch in the UI layer because if you close or minimize GoodTask and re-open it, the duplicate will be gone.
