Dead information wrong from my leaseholder paperwork

Hi. I wonder if anyone can help me. I am in the process of trying to sell my property but my deed information is different from my leaseholder information I have been given from my solicitors. My property was a Right to Buy from the local authority in which they have stated I have 97 years remaining on my lease. However, the Land Registry information given to me by my solicitors states 125 years from the sale 6 years ago which would leave 119 years remaining.

My solicitors have now gone into administration so is this something your company can assist with directly please?

Kind regards

Claire
