Guest network not anymore recognized by reforis

Whatcould cause that reforis not anymore recognize the Guest WLan as such? I plyed around on LuCi and now the guest WLAN do not appear on reforis.

I get this on a regular basis.
Guest Network Setting in reforis switches off when I change firewall rules in LuCi. Even not touching the guest rules.

I just have to enable the Enable Guest Network switch and press the save button and all settings are still there.

Hi, same for me, seems to me that this problem started with some of the 5.x release last year.
