2 Bridge on Mikrotik goes stuck

I have 2 bridges and I’m running a DHCP server on Lan Bridge (ether5) but in the DHCP lease, it shows Bridge Port ether2. While I have another bridge on ether 2.
Why do my DHCP Leases go on Bridge port ether2 instead of ether5_LAN

Before going in depth…why 2 bridges?
And can you share at least your config?

/export file=anynameyoulike

Don’t forget to remove serial and any other private information (like public IP)

Dear I have removed this configuration

Why do you need 2 bridges?
