Word Report shows a "0" instead of blank field

Kappa

I have created a Sales Invoice with the new Word Reporting tool. It works fine, but I have one issue: when I have a text line as sales invoice line, it shows a "0" when it should be blank space. So despite it being a text line, it shows in the Quantity column "0", unit price "0,00" etc.

Is there a way to not show these variables? It simply doesn't look good.

We have used a text variable instead of decimal and converted decimal to text if <>0 and left it blank if =0
