Issue with completed Garmin Coach Plan

Hello. I completed half marathon race yesterday. Started the workout from my Instinct 2 watch from calender. The workout was twice in Garmin connect before the run,bso after the run, I deleted the one that did not disappear, which now it seems, was probably a mistake as I deleted the event. The issue is, I now cannot access the completed plan! When I click on it, the pop up appears and I can't do anything. I don't want to find new event as I already finished the race but even that doesn't work as it always ends with "something went wrong" Any way to fix it? Get rid of the pop up? The plan is completed. Thank you...
