Hi, Cody. Sorry you’re experiencing this.
While we don’t provide support for or guarantee compatibility with non-default WordPress themes (like Twenty Seventeen), I can suggest a few things:
Please deactivate all non-Modern Tribe plugins and custom code and see if that helps narrow down the cause of this.
If it doesn’t, please enable WP_DEBUG and WP_DEBUG_LOG and share any debug messages you see while navigating the front-end or wp-admin areas of your site.
You might also see if you can spot any console errors at your site, particularly on pages where you think Filter Bar should be appearing. (If needed, you may reference our KB article Using Google Chrome Developer Tools.)
If you can’t figure it out, please provide a link to your Events page where you think Filter Bar should be appearing, and also provide me a copy of the latest version of your theme so I can see if I can replicate the behavior on my local testing site.
Let us know what you find out.
Thanks.
