Copy and past seems hit and miss

I think I saw this somewhere else but cant seem to find the thread.

I'm having trouble with copy/paste function in the new release. After a few copy/paste tasks within a drawing it seems to become a bit of a lottery a to what will be pasted. rather than paste the item I most recently copied it sometimes pastes the item I copied a few tasks previously.

My other issue is this is not consistent, if I have say items 1,2,3,4,5 and hit paste a few times with no further copying I may paste item 2 and 3 then 2 again. This appears to get worse the longer I have been working on a drawing.

Is there some way to clear the clipboard memory so it only holds the last item copied?

 

Any advice welcome
