Explain the API unlabeled returned value

Hi all,
I am looking to get some more information about the “unlabaled” returned values from the API.
So I have a company (companyA) that has 2 deals (dealA and dealB).
DealA has only 1 primary association which is companyA (DealA → CompanyA)
DealB has 1 primary association → companyB and 1 non primary association companyA
1) Why is the ‘_unlabeled’ context of the type value. Does it only indicates this primary/non-primary association?
2) Also why (DealA → CompanyA) has 2 returned values. 1 with type company_to_deal and 1 with type company_to_deal_unlabeled?
I am using the endpoint

crm/v3/objects/companies/companyA_ID

Hi @ASpyropoulos

Basically unlabeled means no association label. and primary is also an association label.
