Probably need the actual playbook and actual role to see why this is happening.
Is the role tagged, if so how? Though if it were tags you'd expect to see output even when skipped.
Maybe make sure that you are running the playbook you think you are running, and check that the role that is being skipped is definitely being referenced by the playbook. Check things like the roles_path. And check that the contents of the role are not commented out or something silly.
Also, check that the output you expect from this role is the output it will actually create - maybe you are looking for something that the role is not actually doing!
