Bug snapshot : Can't normally configure wifi client <-> with luci

I don't know what causes this with Tenbay T-MB5EU-v01 boxes but it happens when I want to connect another Tenbay in AP mode from Luci

Luci's behavior is strange because the configuration window never closes.
By insisting there is nothing to be done
Finally forcing it to close with the cross I then find myself with several identical clients to memorize
I then remove the duplicates and it works

This behavior is bizarre to say the least

Another problem remains that I cannot link the client WIFI to the lan. It only works with a WWAN

I have to use the console and edit the network and wireless files to change the wwan to lan

Is it Luci who is causing this?
