If you are worried about being out of status due to this gap, there is nothing to be concerned. This is a USCIS determination and you are in active status as long as the file is in initial review or in RFE. It is another matter if your employer revoked your H-1B on January 31st by writing to USCIS but I doubt such an action was taken.

Thanks Sandeep for your reply !!!
I spoke with my company immigration team and they said it is not an issue as long as i have my approved extension of stay. still i need to get my I-94 document and my spouse H4 is still in ‘case received’ status.
