NCONFIG not working / Error decode?

I am having problems with the NCONFIG settings.
When i do the AT+NCONFIG=CR_0354_0338_SCRAMBLING,FALSE or the AT+NCONFIG=CR_0859_SI_AVOID,FALSE
command followed by the AT+NCONFIG? the response always shows:
+NCONFIG:AUTOCONNECT,TRUE
OK

It never show the other to settings.
What am i doing wrong?
Should there be quotes around?

Bit more info:
when i do “AT+NCONFIG=AUTOCONNECT,TRUE” i get back “OK”
when i do “AT+NCONFIG=CR_0354_0338_SCRAMBLING,FALSE” I get back responce CQ*⸮J⸮ (in Hex: 43 51 2A AA 4A D5)
I assume it is some kind of error indication. How to get the ERROR code out of there?
