RT-AX88U and AC86U mesh guest network remains active

[Gravityz]

i recently installed an aimesh network with RT-AX88U and RT-AC86u
everything working fine so i decided to test out the guest network functionality.
i noticed you can select all(guest network is repeated) or router only.

i put the setting on all and the guest network indeed was repeated by the RT-AC86u

now i switched the guestnetwork off but it seems it is still repeated by the RT-AC86U

the only way to switch it off is to switch off the RT-AC86U, switch of the guest network on the RT-AX88U and then put the RT-AC86U back on.

this seems strange
