H4-stamped but last case is still pending

In November 2018 my last H1B extension got approved but my dependents H4 applications are still pending meanwhile we went to India and got stamping for all (including dependents).

If i file extension for my dependents now(July-2020) will it impact the approval since the old case is still pending status though she is having valid stamped visa?

The old pending case can be withdrawn now.

The pending case should not affect the new case.
