ITC of IGST on import is not reflecting in GSTR 2A

Since may 2021, itc of igst on import is not reflecting in GSTR 2A for some of bill of entries while the same is already there in icegate portal. I have also raised grievance and also tried the functionality of "search BE" in GST login but yet so many bill of entries are not reflecting in GSTR 2A and GSTR 2B. Is anyone facing the same issue? ....
