regmeasure navalue option does not work with -ve value

Hi

I am trying to add a measure from backend using regmeasure and the navalue for the measure is -1 . I get the following error when entering the following command.

regmeasure -d . -add meas_temp1  -type real  -baseint sdc_ocsk -label "meas_temp1" -db meas_temp1 -navalue -1 -defspread repl -basestate write

regmeasure: Invalid Argument: -navalue        

I tried escaping the - with / and this also did not work.

regmeasure -d . -add meas_temp1  -type real  -baseint sdc_ocsk -label "meas_temp1" -db meas_temp1 -navalue \-1 -defspread repl -basestate write

regmeasure: Invalid Argument: -navalue          

RPAS version is 13.4.1.11.1

Thanks

Nick
