Registered customer in portal shows as salesperson on Odoo 9.0
I have setup odoo 9 for my company about a month ago and started issuing quotes and invoices. I have noticed that when a contact/customer registers on the customer portal, it also shows up on the salesperson dropdown selection for invoices and quotes.
I confirm the customer does not have access through the portal except viewing his account billing (quotes/invoices/payments).
Portal access management has "Other/Extra rights" selected.
I checked on my sales team and only internal users assigned to the team are shown here.
Is this normal? Am I missing something here?
Thank you in advance,
