Birth certificate problem and residency

I'm a British woman married to a Moroccan (from Marrakech).
I'm hoping to apply for a Moroccan residency permit but have a question regarding my birth certificate:
When we got married in Marrakech last year, the Morrocan authorities insisted on keeping my original birth certificate and left me with just a photocopy. Our marriage certificate mentions my birth cert and it's unique serial number (this appears in the top right hand corner of a full UK birth cert).

This meant I had to contact my local registry office and obtain a new "original" birth cert after returning to the UK. They isssued this for a small fee and it's the same as the first one but the serial number in the top corner is DIFFERENT to the one used for marriage purposes:

I know an original birth cert needs to be provided when applying for Moroccan residence card but will it matter if the serial number on the one I now have is different to the one shown on the marriage certificate?

Have any other Brits been in this predicament? If so, how did you get around the issue and do the Morrocan authorites understand that each replacement UK birth cert has a different serial number (even though all other details remain the same?)

It's really not my fault that the Moroccan authorities kept the first one, I tried hard to get it back but they wouldn't let me have it back

Please advise! Thanks
