Completed tasks re-appear and then go away after a refresh

Curious if anyone is seeing this: when I complete a task, about 50% of the time it gets marked as done then gets marked as undone again quickly. If I go to the Reminders app, it is still correctly marked as done. If I force a refresh (cmd-R) in Good Task, it also then gets marked as done and stays that way. Maybe a race condition in the code between the local database and the remote database?

Thanks for the feedback. Would you try below?

Settings - Advanced - Delete local cache files
Restart the app and device

If the issue persists, please share some more details including OS version, device, etc. Thanks!

Thanks. Seems better now, will reply if I see it again.
