wrong date of birth on L-Visa

Hi,
I am in China, my Mrs and my 3 month daughter got L-Visa.
But embassy in Pakistan mentioned the year of birth wrong for my dauther.
They mentioned 1912, while it should be 2012.
All other information is Ok on L-Visa and the code mentioned on the bottom of L-Visa is also Ok. In which Passport number and date of birth mentioned Ok.
1:-Please suggest should we get new visa or no issue and my daughter can enter ?
2:-If we need to get new L-Visa then Is it possible to get L-Visa in same day as we have to go from another city again ?

Br,
Kashif
