Edit window closes/ Wont stay open!

Over the past month or so, anytime I have tried to edit a pre-existing regular call, the window will close within 1 second of clicking the edit button. It won’t stay open for me to make the changes and just closes automatically. Please advise!

Also I recommend adding a duplicate button/option for those who have multiple “regular calls” about the same topics, so we can just duplicate the “interview” or “Regular Call” instead of going in creating everything from scratch again.
