Landlord has put the wrong surname on my lease, should I be concerned?

Hi,

I’m about to move into a new property short term and the landlord sent over the lease documents to sign. We previously had issues with me passing the credit check due to an unknown CCJ however his response was “don’t worry I’ll sort it”.

2 days pass and he sends me over the lease, and under the section where it mentions my name the surname is completely different.

I didn’t notice until I clicked sign (my own fault) should I be worried in anyway?

Many thanks
