Calendar Clicking Issue

[derekwan1]

Clicking on the date/time boxes should bring up calendar/timeslot popups. However, on many laptops (including my own and several AI's trying to check in), the popup immediately disappears after clicking on the date/time boxes. Safari seems to be fine, but this is a problem on Chrome

Update: clicking on the date/time boxes on the very far right will let the popup stay. The popup disappears if you click in the leftmost ~1/3 of the box
