Can't change cha**et in WiFi settings - GPi Case

[jsit]

I have a Retroflag GPi Case with a Raspberry Pi Zero W running Recalbox 9.2.3-Pulstar. All the configuration is the default that gets set when first booting on a GPi.

In Network Settings, I'm unable to "change cha**et" (character set*) to get lowercase letters. It looks like I'm supposed to use up/down for this, but those buttons don't do anything.

Any tips? Thanks.

* A profanity filter seems to be modifying "char-set"

@jsit I think I remember having to first setup the controller (assign the keys) in order for that to work.
