Weird warning with bridge config regarding VLANs

Well, not surprized as you have an overly complex non-standard vlan bridge configuration.
Read through this link to fix…

For starters the only thing that needs to be done for the bridge itself is enable it, keep default pvid=1 and dont add anything such as admit only vlan tagged frames etc…

This particular rule demonstrates you dont have a clue about trunk ports, access ports etc…
Not that its a bad thing but time to learn properly vice configuring using some horrible youtube advice.
/interface bridge port
add bridge=br-trunk frame-types=admit-only-vlan-tagged ingress-filtering=yes
interface=ether1 pvid=2

Thus read through the link, and look for the similar AP example.
THen post your new config if you hare having issues.
