Who knows how to get rid of this auto generated symbol inside barcodeField? It creates false sense of available data thereby affecting my coding logics. The screenshots of both the Interface and expression are attached.

That looks like the "infinity" symbol that's sometimes displayed when you attempt to display an integer data type that's too large (which doesn't take much). What do you have the value of "local!barcode" set to? I'm not incredibly familiar with how this field functions but it seems it might be relevant here. Also I suppose you should double check that the value isn't null, since (just guessing) that might cause wacky results too.
I am very happy for your willingness to help. People like you make the world a better place. It looks like an infinity symbol. The value will change dynamically based on the user input. It is stored in a local variable only for now. Just wish I could stop the symbol from auto generating
