I do not know what kind of lawyer you have but he shouldn't be updating forms with the facts that occurred after the date of signature on the form (such as A number, basis for application (no more pending I-140) without getting new signatures.
For rejected applications, he can resubmit with the same packet if the error was in check only.
IMO, if the error was in form and if the error has now been corrected or the form has been updated even if there were no errors initially, you (the applicant) would need to review the changes and sign with the current date after you review.
Since the lawyer has already made errors twice, he doesn't deserve much compassion.
Thank You
