Can't create new WAP community (WPA-PSK error)

[jamesmknox]

We have an HPE M330 dual band radio (WAP)... works fine.  I am trying to add a new "community" with a new VLAN to one of the radios.  However, no matter WHAT information I enter, including letting it default, or have no security, the result is ALWAYS the same.  I get an error:

     "The WPA-PSK key is incorrect: The string is 0 characters long"

I have also tried selecting the "WPA Personal" security and entering a valid key (and confirming it).  Doesn't matter - always says the key is zero length.  This has just got to be something very stupid that I am diong wrong, but what?   TNX
