Multi WAN select DNS

[lucasarnulphy]

Hi,

I'm trying to setup a multi WAN configuration using this guide :
https://docs.opnsense.org/manual/multiwan.html

I have an issue during the part in which I should assign dns servers to gateways (step 3).

When I click the save button after selecting the gateways in the "use gateway", all the selected values disappear and the values are set to none.

Does anyone have an idea what the problem might be ?
My current configuration for gateway single/group is attached.

It is supposed to create a load balancing between FIBRE_GWv4 and WANGW using OPT2_GWv4 as failover.

Thanks a lot,
Lucas
