Unable to delete completed tasks all at once
I'm unable to delete completed tasks all at once on a specific list - normally I'd go to the top right hand corner and click the little 'task actions' button then click 'delete completed tasks'. It's still asking confirmation, but once you click OK nothing is happening - the tasks are still there.
It's also only happening on my shopping list project, which I generally don't put due dates on - the other projects (which usually have due dates) seem to have done tasks disappearing as usual. I just can't figure it out!
Any help would be appreciated.
