How do I cancel a Meet & Greet?

I have 2 M&G's on my calendar that needs editing/deleting. I'm not seeming to find a solution on their website.

The Rover calendar imports into my Gmail calendar so I can't delete this in my Gmail calendar. Can't seem to do this on http://Rover.com or app. either.

Has Rover fixed this problem yet? Last post on this was July 2016?

Thanks everybody!
