BG96 FTM error: invalid <band>

Hello,

While getting a device ready for radio testing. I can get the device in test mode using the following command:
AT+QRFTESTMODE=1
after restarting the device i can see the testmode is active:
AT+QRFTESTMODE?
+QRFTESTMODE: 1

After test mode is activated and i use one of the commands from the Quectel_BG96_RF_FTM_Application_Note_V1.0 i get an error from the modem saying:
ERROR: invalid

examples of commands used:
AT+QRFTEST=“GSM900”,122,"ON,0,100
AT+QRFTEST=“LTE BAND1”,18300,"ON,50,1
AT+QRFTEST=“LTE BAND12”,23095,"ON,50,1
AT+QRFTEST=“LTE BAND2”,18900,"ON,50,1,100,0,50,4,0

all returning the same: ERROR: invalid < band >

Is there any command i’m missing or something that i’m doing wrong here?
