Here are two examples:
Date/time changes from current (7/22/21 10:40 AM) to correct event date (9/27/21 6:00 PM) upon simple browser refresh. Venue field is empty when current date is shown.
Current date/time is displayed (7/22/21 10:00 AM). Browser refresh has no effect. Date/time is changed to correct event date when style is changed with style picker. Venue field is empty when current date is shown.
Seems to be a strange timing/caching issue with the displayed data fields.
