Map/Add to Calendar Buttons | WordPress.org

Those buttons appear if there is a location and/or a URL found in the event data. If there’s not, they won’t.

Hopefully these screenshots come through

Looks like they didn’t. I added them under the calendar at fbcthibodaux.org/calendar

I see what’s going on. You’re theme’s CSS is rendering the buttons invisible with .button {outline: none; border: none; color: #fff; ...

Try styling just the calendar buttons with .pgcal-container .button {color: #000;} etc.
