This has nothing to do with Prometheus or other scripts. The core requires a vmbr network

Is there a template which I need to adjust to use the right bridge or what do you mean with core?

whats your right bridge? you have 2 active. thats weird. You can run the scripts advanced and enter the correct bridge.

If i use an alternative bridge, i can only choose the first one

Ah got it. Just tried your test version. The default version keeps using vmbr0. With the advanced version I could successfully allocate the network to the right bridge. I have two currently and by default I would use the one that has the gateway field entered.
