Error in GUI in multiple gateways with load-balancing

p_tp1 is pppoe,
x.x.x.114 is a gateway on ethernet interface (wan3-mts)

Is everything OK here? Why “gateway” is in red? When I add address everything is OK, but if I open it again – it’s in red with “@unknow” added. If I place x.x.x.114 at first it become second after opening.

I’m using PCC load balancing. It’s seems to me that laod balancing is not actually balancing traffic correctly, but I’m not shure.

V5.18.

Thanks.
