Howdy efromdc,
That is unusual. I’d be glad to help you figure this out.
Do you have any theme overrides for the Events Calendar? If so could you try disabling them by renaming your [themename]/tribe-events/ folder to ‘tribe-events-bak’. Does the issue persist?
From the look of it this issue is quite likely caused by a customization, as I am unable to reproduce it in my tests. If the boave did not work, could you please run through some more diagnostic steps? Could you try temporarily activating the default 2013 theme, and seeing if the issue persists.
If the issue persists in the default 2013 theme, then we have a different set of debugging steps. Please keep the 2013 theme enabled, and also disable any plugins other than the ones from Modern Tribe to see if that fixes is. If it does, please try reenabling them one at a time until the issue resurfaces.
Please let me know what you find out. Once we have narrowed down the problem by following the above steps, we can see about fixing it. Cheers!
