Setting up a new database and when I go into accounting and click on "customers" and "vendors/suppliers" respectively, it always shows all contacts. As of now they all have the supplier rank of 0,  and in my understanding, none of them should actually show up as suppliers, but Odoo shows them all.

Can you help me how to make that distinction so that only the ones needed will show up? Working with Odoo V17.
Thank you
