L2 Visa with wrong mother's date of birth

[cryptpred]

Hi Experts,

Currently I am in US on L2 visa. By mistake during stamping process I entered wrong date of birth for my mother in DS160, and I got L2 visa with that mistake.
Now my question is regarding L2 visa extension process. During extension process, should I enter correct date of birth for my mother in DS160. Will this lead to denial of my husband's L1 and my L2 visa extension.
Kindly advice.

Thanks!

How big is the mistake? Is it just a simple typo or totally different date?

Usually L2's mistake won't impact L1's extension.
