J+ jogging command not working in Macro

Im using J+ for the buttons on HMI VMX which works well.

Also, Im using macros for sending commands. All standard commands are working like

1:CLR=1(BIT)

but the only exception being

1:J+=1(BIT)

checking the code in the macro editor show that the code is ok, but trying to upload to VMX throws an error

Im assuming that J+=1  is mis interpreted as J += 1  (so adding 1 to J known from C like languages)
