I apologize if this question is very obvious, but how do you delete backups? I've tried searching online, cobian's forums were shut down 3 years ago and their archives didn't help me (or I missed the right solution). I see I'm supposed to go the history tab of a task but the tab is completely empty and the history options on the top are all greyed out. Again, apologies if this is actually obvious but I can't seem find a solution via web search.
P.S. I have used this program three times and deleted the first two tasks somehow thinking it was a good idea at the time.
