Workflow - AOS Quote modules doesn't put Line Items table in email

In SuiteCRM 7.2.1, generating an email template using the string

 $aos_quotes_line_items

does not actually put the lineitems table into the email.

Using other strings such as:

Part Name:

$aos_products_quotes_name

List Price:

$aos_products_quotes_product_list_price

Unit Price:

$aos_products_quotes_product_unit_price

Description:

$aos_products_quotes_item_description

Name:

$aos_products_quotes_name

…will occasionally populate with either the first or the last item, but not the whole set, and even this is unpredictable. This is whether Groups are used (Quote groups that is) or not.

I would expect, or at least like, to see this table being inserted into the email by use of the $aos_quotes_line_items string (although formatted as it is on the Quote module, not as it shows here thanks to BBEdit):

Group Name:	Parts for something he needs
Service	List	Discount	Sale Price	Tax	Tax Amount	Total

1 logitech mouse p/n 1234567 $50.00 $10.00 $40.00 0% $0.00 $40.00
2 bluetooth toothbrush (blue) p/n 12324238 $80.00 - $80.00 0% $0.00 $80.00
3 another part, #123456 $120.00 - $120.00 0% $0.00 $120.00

Total: $250.00
Discount: $-10.00
Subtotal: $240.00
Tax: $0.00
Grand Total: $240.00

How do we fix? Alternately, how do we use Workflows to email a quote?

Thanks,
