cannot create tickets

[cwerner1]

Setup: ERPNEXT with Helpdesk

I've an Erpnext instance with multiple Customers and Contacts Mails. (Doctype: Customer)
In Helpdesk I didn't create my Customers (Doctype HD Customer)

When I want to create Ticketin the CustomerPortal or email: Helpdesk finds my Contact Email in the Doctype Customer (CUST-100xx) and wants to link the HD Ticket with the Document Customer:CUST-100xx. - which is not valid.
