Gs1 Symbology Specific Option S’abonner

Hi 

I am using bartender automation 11.0.2.3056 

I created a GS1 label which worked great for a while until the human readable text on the barcode became a single line and without brackets which was not what i designed 

when i went to the human readable text >symbology specific option it was not highlighted 

I don't know what went wrong and what caused to do that 

any ideas?

thank you
