GSTR 3B filing For March 2018

I am facing issues for many of my clients, the data is not getting saved in GSTR 3B filing for the month of March 2018 in itc and itc reversal head only but in outward supplies it is getting saved.
I called department but they are saying to wait as there is some technical issue but today is the last date.
Any body facing similar issues and got the issue resolved?
