Unable to use Product Name multiple times in PDF Template

I need to use a Product Name in a PDF quote multiple times in the same PDF document. I’m using $aos_products_quotes_name to output Product name in different parts of PDF template. When I generate PDF Quote, it correctly outputs real product name in the place of first occurrence of $aos_products_quotes_name, in every next occurence it only outputs the “$aos_products_quotes_name” (name of variable). Can anyone help?

Can you attach an image please


Kakaový prášok alkalizovaný PV6 is our produkt name. In next line you can see only $aos_products_quotes_name. All product line and product groups are affected.

see screenshot. Thanks for your interest.
