Although it's the same Skill Test, I gather that the UK CAA is entering 'CB IR' as the licence endorsement....
The people issued with IRs in this form need to all immediately send them back to the CAA with a polite demand that they be re-issued correctly.
The longer they get away with this, the harder it will be to get it put right.
