Education detail mismatch in previous and current DS160 for H4

By mistake, the education level of my wife(H4) is mentioned as high school in previous DS160. Visa got stamped. This time I filled new DS160 for her and mentioned correct education level(Inter). Will there be any problem in stamping this time. Do they match previous and current DS160.

If they ask question, is it safe to say that we filled it by mistake.
