OP, as has been stated at least twice now, ifyou submit a SD to the Traffic Enforcement Centre in time then the OfR and Charge Cert WILL BE CANCELLED, it's the law.
As you now have another PCN you can see the relevant legislation - it's printed at the top of page 1.

Contact the council to see if an OfR has been issued, if so what's its date?
Alternatively, as said by others look online and check the outstanding sum. If £205 then it's been registered.
