Search Console – invalid object & value type for field “location”

In Google Search Console under Enhancements > Events, I’m getting four errors. Two for “Invalid value type for field ‘location'” and “Invalid object type for field ‘location'” for the two URLs listed below.

Both of them list a venue as you can see. None of my other events are showing for this but it is a new website and the others may not have been indexed yet.

I had an error there of Missing field “location” on a different event but it was corrected when I added a venue.

Thanks ahead of time for your help.
