Calendar Not Copying Events Correctly

Hi,

So i have recently updated to the recent OS. Before i did this i could copy and paste the events correct.

So for example i right clicked on event 1 and it copied everything including the notes section and i pasted it into event 2 title and it pasted everything from event 1.

However i do this now on the updated calendar and it doesn't do this anymore. Is there a reason for this? As i have to now do a long work around...

Please help guys 🙂
