Hello,
The asterisk is there to indicates the vendor that he should provide a name.
But, because the vendor registration can be automatic via some HikaMarket settings ; we can't make the field strictly mandatory.
So we added some checks to fill the vendor name with the account name.
Regarding the edition in the backend, yes we can add some checks to refuse that an admin empty a vendor name.
