Howdy Michael,
You might be able to fix that with some CSS like `.single-tribe_events .tribe-events-event-meta{max-width:600px;}`
I just want to mention there is only so much we can assist you with when it comes to CSS modification, especially when you have lots of changes. Our scope of support dives into a bit more detail here, but when it comes to modifications like these we tend to offer a general overview of advice, and it is up to you to apply that to your specific site. Both Geoff and I have kind of violated that rule in your topics. We like to do that whenever our manager is looking the wrong way. But seriously, just so you know this is not something we do on a regular basis because it is not actually covered by our support. If you are in need of further CSS adjustment to integrate your theme and Events Calendar, you might end up needing to hire a developer.
Thanks for posting! I hope that works. Let me know if you are in need of some more advice/overview on how to make modifications. Cheers!
