why is the validator showing multiple times the same location in structured data

hello, we are using rankmath pro for our structured data and when i validate it it shows multiple times the same location.

Could you look into why it does it that way: https://validator.schema.org/#url=https%3A%2F%2Fwww.steinbock-partner.de%2Farbeitsrecht%2F

In the quellcode of that page: https://steinbock-partner.dev-wp.de/arbeitsrecht/ – it only shows 2 times the location in Wuerzburg but not 14 times.

PS:

Also maybe as sidenote i tried to use your rm locations for our 8 places but it somehow never showed more than one of those i configured.
