Hi Erik,
So sorry for the trouble here! This is indeed a known issue and the good news is that we are in the middle of working on a fix for it that is scheduled to be included in our next maintenance release.
I’ve added this thread to the ticket in our system so we can follow-up with you when the fix has been released.
In the meantime, some others have reported that adding this CSS snippet to your theme’s style.css file works as a temporary solution:
.tribe-events-filters-vertical {
float: left;
width: 25%;
}
Thanks so much for reporting this and for your patience while we work on it!
Geoff
