The steps that I follow are the following:


1. I created a "Many2one" field by selecting the "Person Type" template
2. I change the name of the field because I don't want the technical name to be a random name, for example:
x_studio_many2one_field_bgN5V

I am interested that the technical name is for example: "Person Type".

I understand that the "Conctacts" module is related to "Users" and it creates two fields that are linked. But, it also leaves me a field with the name "x_studio_many2one_field_bgN5V" which is an error.

See the fields:

When trying to delete it, it tells me:

This column contains module data and cannot be removed!

I think the Odoo experts should fix this problem.
