Q: I had an update for iMovie notification 25th June but before I had chance to update it was replaced by a further update and now the former update cannot be downloaded and I want to delete it from the system as the APP shows one update due

My system showed an Update for IMovie , this was received 25th June, before I had a chance another update was received and was downloaded but the system still shows 1 update (first one) still seeing downloading but the system will now permit. Can someone please suggest a solution.
