Unwanted association when associating contact to company

Question

My problem is that i get unwanted association when associating contact to company. As it can be seen below i create associations for two contacts to same customer, but the result is that they both get two type of association, eventhough I only have specified one.

I am posting following json on {{baseUrl}}/crm/v4/associations/contacts/companies/batch/create

{
    "inputs": [
        {
            "from": "11751",
            "to": "9314823150",
            "types": [
                {    
                    "associationCategory": "HUBSPOT_DEFINED",
                    "associationTypeId": "1"
                }
            ]
        },
        {
            "from": "11752",
            "to": "9314823150",
            "types": [
                {
                    "associationCategory": "HUBSPOT_DEFINED",
                    "associationTypeId": "279"
                }
            ]
        }
    ]
}

"associationTypeId": "1" is company_to_contact "associationTypeId": "279" is company_to_contact_unlabeled

when I get the company on {{baseUrl}}/crm/v3/objects/companies/9314823150?associations=contacts is there assosiations not specified in my create association request;

{
    "id": "9314823150",

    },

        "contacts": {
            "results": [
                {
                    "id": "11751",
                    "type": "company_to_contact"
                },
                {
                    "id": "11752",
                    "type": "company_to_contact"
                },
                {
                    "id": "11751",
                    "type": "company_to_contact_unlabeled"
                },
                {
                    "id": "11752",
                    "type": "company_to_contact_unlabeled"
                }
            ]
        }
    }
}

How to avoid the association not specified in the create association request?

Answer 1

I know what the problem is now. When creating firsts association for contact to company will the association always be the contacts primary connection to a company. By bad was that is saw the association as the company primary contact and not as the contacts primary association to a company.
