Did you file any I-130/485 paperwork based on your marriage or is her 485 pending based on her parent's sponsorship?
In general, a person does not want more than one 485 process filed and pending at the same time.
You should consult with an immigration attorney who can review her facts, advise which option is best to complete her green card process, recommend a course of action etc.
