Wrong endorsement code on licence??

[ZZR]

I've just noticed that a previous and still valid endorsement for speeding has the SP50 code on it, however this is for speeding on a motorway, but I was driving on a dual carriageway at the time of the offence.

Is there anything I can do about either trying to get it changed or having it anulled?

I think it should be an SP30 as the offence took place on the A120 in essex.

So approach the Magistrates first then if no joy DVLA?

Cheers,
