Problem while I'am editing Template

Problem while I'am editing Template

Hello

I created inventory template for production and I used those two fields below:

      ${Quotes.Qty}
      
      ${Quotes.Total After Discount}

  • I ensured that product details iteration are present under<tbody id="lineItem"> and </tbody> tags.

 I know it did correctly because everythings was working.

But since the upgrade of Zoho CRM when i'am editing my template I can't save it and I've got error message:

      "Unsupported Fields: We recommend that you remove them from this template because they cannot be used in merge fields."

But I cannot remove these fields because I need it in my document. 

It worked very before, how can I fix this problem??

Thanks in advance

Regards
