So long as her adjustment of status (I-485) case is pending she may remain in the United States. She does not need the I-120 renewed in order to remain while the I-485 is pending.
I am assuming that you have satisfactorily submitted the requested documents. If so, your decision should be coming soon. If for some reason your case is denied because you failed to submit sufficient documentation you can refile the adjustment case again if necessary,
Best of luck,
