Redwood Unable to see Add Contacts button in Supplier Creation or Supplier Management

Summary:

I am testing enabling Supplier Management in Redwood. Business process is to use the Create Supplier option, the client does not use Supplier Registration.

When creating or maintaining a supplier the user cannot see the Add Contacts Button, on existing suppliers they can see contact details but cannot edit them. In the classic UI the same user is able to add and edit contact details.

I have added the below privileges to the custom role:

Maintain Supplier Contact

Maintain Supplier Organization Details

And ran LDAP processes, the user still cannot see the edit option for contacts.

Has anyone else come across this issue?
