[Events +] Events+ when adding more than 1 date for an event, start/end times can't be entered

When trying to enter the times for an event that has more than 1 date, the start and end time fields do not become active to be able to enter a time – no time selectors show and the time cannot be entered manually either. I've tried upgrading the php on a staging environment, and updating all other updates, and nothing seems to be causing a conflict. Is this a new bug?

Thanks in advance,
