H4 extension via I539 has been approved with Class as L2

My Wife's H4 extension has been approved with an incorrect class as L2.

 

My question is

 

1) If this is a typo, how do I get this corrected. Current i94 is only valid until 8/1 and this new approval notice starts from 8/2, but with an incorrect class. Will this be an illegal stay after 8/1 until this is corrected? She is not working currently.

Call the CBP maybe at your local International Airport and then see them to have it corrected.
