I also have this same issue. Venue data sometimes is added, often multiple times, to a single event in the admin view. However, the live view of the single event displays blank for venue. Interestingly, though, on venue pages, the new events do show under the correct venue. So it appears to be saving the venue date somewhere, but not correctly for all views.
I will also note that I did update to the newest versions of all plugins and got fatal errors, killing my whole website, on multiple attempts and after suggested debugging processes.
