Unfortunately, we can't do that directly, but you can delete the completed task on this list and the counter will decrease as you do.
Thanks. Unfortunately, I have already done so but the completed tasks is stuck at an earlier number. I want to clear this number and start over if possible.
Karma is turned off.
This happened to me as well.
I deleted all completed tasks from all lists. Then I deleted all tasks. Then I deleted all lists. Then I deleted my account and recreated it. Nothing made my completed task count go down.
Please log out, clear the cache for you browser and sign back in. Does the count still appear wrong?
