Product Description not showing in Invoice (via CRM)

Product Description not showing in Invoice (via CRM)

Hi,

When I make an invoice from my CRM and manually put text into the box underneath the product, it shows as visible in Zoho, but disappears when converted into PDF. 

I believe my template needs to have a code that is not ${Product.Description} (or similar, that was from memory. Before the update it worked fine, however if I want text to appear here, I have to go into the product, add that specific text into the description and then select that product in the invoice - a little time consuming and back to front?...

Please help/rectify!
