Think there are some issues with your config, specifically VLAN related. I prefer to use explicit VLAN’s and try to avoid VLAN 1 where ever I can.
I used this nice topic to let me be inspired:

Be aware that setting the correct VLAN on a wifi interface is done on datapath (configured on the CAPsMAN). When using, check the last config for the AX devices, called “cAP AX wifi configured via CAPsMAN datapath VLAN”.
