They will correct it when you go for Biometrics. I had the same issue, my name in the notice came correctly but found out they made a mistake when i got to my Biometrics location. They changed it there and asked to call USCIS to create a ticket.
However, My EAD came with incorrect Name, So i created a ticket again . They told me to send the EAD with a copy of my passport so they could send me a corrected one.

Hope this helps.
