Edit Popup Issue

I've run into an issue with editing JEvents via frontend of our website https://www.ycbk.org/calendar/eventdetail/30/-/centennial-banquet The modal popup box doesn't display completely thus not allowing my users to edit events on the frontend.I have attached a screenshot of the page. I know Joomla 3.9.0 is out but I wanted to resolve this prior to upgrading. I am using Joomlashine template JSN RETA PRO Framework: 3.2.4 - The latest version. Template: 1.0.2 - The latest version.

If anyone has run into this problem and has a solution I would greatly appreciate guidance.
