Hello,
This is a known issue and it has already been reported to RnD.
The issue is that configuration of the VLANs has two options, vlan and vid. You can view them by logging to the router and executing the command:
The issue is that vlan value can only be set as high as 128, however, currently, it is incorrectly parsed, given the same value as vid, exceeding the upper limit, as vid can be set within the range (0 - 4094), creating your issue.
The suggestion is to edit option vlan to a value under 128 via SSH, or revert to a working firmware until the version with the solution is released, which is currently in development.
Apologies for the inconveniences,
Best regards,
