Hello,
I got the impression that there is a mis-understanding.
I would assume would be assigned to all new vendors when the register
What do you mean with "assigned to all new vendors" ?
In my previous message, I explained you how the template feature is working :
When a vendor do not have a product template set ; the default product template will be used automatically.
So yes, it is normal that there is no product template assignation since the "default" is used when there is no assignation.
The setting is not there to perform an assignation ; it is there to provide the default (fallback) value.
And you can override that value for your vendors in case that you want to propose a different template than the default one.
The counter of assignation is there to indicate how many vendors have that assignation but for the default one, there is no counter and the value "default template" will be displayed in the listing.
But if you do set the template to some vendors (while it's the default one), yes you won't see the "default template" information but the counter of how many vendor have that template assigned.
For what I can understand, there is no bug or issue.
Regards,
