Tom, thanks for the update.
Item #5 is a known issue. Sorry about that bug.
The rest of the items seem to be related to the theme conflict / possible JavaScript errors–maybe the same as before or maybe newly-introduced issues/conflicts.
We cannot troubleshoot compatibility specific to Bridge theme, but you might want to provide their support with a .zip of our Community Events plugin and have them do their own testing on it.
Please let me know how this goes for you.
