Vlan configuration issue

Hi

I have Tomate v138 on my router but I have some issues when I setup VLAN configuration.
When I change the original configuration (remove some port on VLAN 1, adding another VLAN) and saving configuration, the router reboot but the changes are not taken into account. The default VLAN configuration does not change.
I cleaned NVRAM after fresh install. I had not issue with v134.

Would you have a fix ?

Thanks
