Errors in Event Structured Data

Hello,
even if event Venue and address are correctly setup (screenshot: https://prntscr.com/lqzprp)

I get errors by Google Search Console and Google Structured Data Testing Tools:

1) LOCATION: Thing is not a valid target type for location property.

2) ADDRESS: Is missing.

Have a look: https://search.google.com/structured-data/testing-tool/u/0/#url=https%3A%2F%2Fwww.swingfever.it%2Fevento%2Fcorso-di-balli-swing-enjoy-swing-2%2F

Is there a way to fix this without editing core plugin files?
