Admin: Event details checkbox labels missing. Can't change venue.

[ghost]

Calendar > Events > under "All Upcoming Events" > click the hamburger menu next to an event and press "Details". A couple problems noticed using both the latest versions of Firefox and Chrome.

1. On the Details screen of an event there are two checkboxes and they are missing labels. I assume they're suppose to be "Published?" and "Cancelled?"
2. On the Details screen you can successfully change the date and/or time, but not the venue. Though you can type something different in the venue textbox, when you hit the Save Changes button, the data reverts. Even tried copying a venue over from another event date, and it still won't save. The work around is to delete the event and use the "Add an event option" to re-enter it. (When I say delete I mean remove an event from the admin "All upcoming events" list by going to its Details screen and unchecking the first checkbox and checking the second one.
3. If you're using "Add an event" and you're on Firefox, you do not get any sort of warning or message if you enter a venue that is not in the venue list. You do get a warning on Chrome of "No matching value found. Add the venue then try again", but for both browsers the Add is allowed to go through, with the event location ending up showing "TBA," which you then cannot change to anything else due to the problem that's listed above in Finish adding SQLite support #2. Both Firefox and Chrome if you leave the venue totally blank, you do get a "This field is required" error message, and the Add will rightfully not go thru.
