$COMPANY_DOMAIN$ linking/referencing issue

Credential Entry: "DomainAdmin" (as below)
Name: $DOMAIN$\$USERNAME$

Username: administrator
Domain: tfg.local
Password: SuperSecretPW1


Credential Entry: "UserCred" (as below)
Name: $DOMAIN$\$USERNAME$
Username: users_name
Domain: $COMPANY_DOMAIN$
Password: SuperSecretPW2

Structure:
Folder (Type: Company; Cred>Credential=Cred Repository: "DomainAdmin")
L > Cred DomainAdmin
L > Cred UserCred: Looks like "\ashley" instead of "tfg.local\ashley", see picture

When the cred User cred is used for RDP with the option (the only one i have tested) "Open (Select credential entry)" it doesn't send the domain instead it uses the computers domain that rdm is running on.
