Management DHCP Client on GPEN21

Hi, today I received a GPEN21 testunit. We want to use it as a fiber to copper converter.
All looks promising but i cannot get the unit to do dhcp request for management on a specific vlan (7). If it boots it does dhcp request untagged.

Is there a way to force swos to use vlan 7 while optaining an IP address with DHCP? We cannot do untagged in the FTTH infrastructure.

Thanks

Got answer from mikrotik support:

Hello,
Thank you for contacting MikroTik Support.
We have observed the same behavior in our labs, and we are looking forward to fixing it in upcoming SwOS versions.
Currently, I can only suggest using a static IP address configuration.
Best regards,

Fixed in 2.13
