Customer Sonos card, remove non-sonos speakers

I’m having confusion and trouble with the custom sonos card. I’ve got the newest beta installed. But I’m confused on two fronts. First, I seem to have 2 url’s in the resources list, I’ve attached a screenshot.

Second, my speaker list is messed up with all my Google speakers, something called RINCON, and I would like it to just list my 11 sonos speakers.

Could anyone tell me why this is so messed up for me?
