High blob count in group repositories

There are some known edge cases with the counts and the totals which cause them to be inaccurate. There’s a ticket that exists: Loading.... My understanding is when that ticket is complete known edge cases will be resolved and there will be a task which allows you to do what you ask and “reset” the counts to the correct values. The task would allow us to see any further anomalies. My suggestion would be to wait until that work is done and see if you still have outstanding issues. Sorry that’s not immediately helpful but at least providing information.
