Hi there,
I recently noticed an odd behaviour on Goodtask 6.8.1 (711) installed via Setapp.
On desktop when moving tasks from the board columns (Data view) ex from today to tomorrow the task automatically switch to another list (every time the same list).
I already noticed a few days ago that some tasks where assigned to the wrong list, I figured it was about sync problems with the built in Reminder app, but I was unable to identify the exact moment that error originated until today while I was rearranging tasks dates via drag 'n drop.
