No VLAN connection

Hello,
I have problems with VLAN tagging on my Cap Lite AP. I want to isolate my WLAN traffic from my Network.
My szenario:

My management Network is default on the uplink tot he AP and the DHCP Server ist also connected tot he switch.


First I create a new Bridge (bridge10) an two WLAN SSIds (iot and wlan50)

Then I put the ports ether1, iot and wlan50 to the bridge10

In the next step I creat VLANs on the bridge (10,50) und tagged them on the Port ether1

When I connect to WLAN 50 I become an IP from my Mangement Network and not from the wlan50 an when I connect to iot I doesn’t become an IP.
The DHCP Server are correctly configured an the taggings configured on the switch.
Has anyone an idea where my Problem is?
