Lede 2.27 ar150 advanced wifi config error when creating multiple client and master configs

in ver 2.264 I could create multiple wifi connections and disable them when needed in the advance config of luci. with no anomilies

now in the lede 2.7 version. If i create a second client config it will rename a master config with the same wifi name. it actually goes into the interface and renames the settings in the interface . please note every new client connection gets its own unique wwanxxx1 name for the interface that gets attached to the wan zone.

I think you operate everything from Luci. So I don’t there is luci is difference in such functions in 2.27 and 2.264.

Can you please check carefully? Otherwise you have to go back to v2.264 because we cannot do anything with luci.
