I have a TL-WPA8631P extender.

It is configured as OneMesh with my router.

It "clones" / "forwards" / "onemeshes" my original primary wifi in my house, however it does not do so for the guest networks which I configured on the primary router AFTER the one mesh has been fully set up.

This is unfortunate and undesired, so I tried setting on it its own guest network, I tried to make it secured with a password however it persists to be without a password even after I specifically set a password and clicked save and it signaled to be saved successfully.

Then I tried disabling the unsecured guest network and clicked on save yet it remained.

It would be ideal if the one mesh would also forward guest networks without me having to redefine such manually. But most critically, if I disable those I expect them to be disabled, this is a huge security issue.
