Mistake on wedding certificate

So we got married 3 weeks ago, and have realised that the town we live in has been spelt incorrectly on our marriage certificate
My now husband thought this was the correct spelling and actually told them him this was how it was spelt and I not having my glasses or contacts didn’t realise the error until the certificate came
How important is it that the spelling is correct? it’s one extra letter Middlesborough instead of Middlesbrough 🙈I don’t wanna faff about getting it changed if it’s not going to make any difference
