Gstr-1 return filing online

Today, i.e., on 29/12/17 - after a long struggle with the offline tool, I got fed up went for online preparation, since due date is nearing and still two more months' filing is to be done. After entering all the details of invoices in B2B transactions, when I went to look for the summary it shows wrong (lesser value)  total taxable value and tax amount. I had checked individually, all my enterings and summed up in a calculator, it shows the correct figures. 

Minute differences of couple of Rupees can be due to rounding off of values. If the difference is huge refresh after 10  minutes.

Once, I refreshed the page and logged out and came in - even after all these trials, the summary figures have not changed. 

If the difference is huge refresh after 10  minutes.

HSN-wise break-up , I had entered 9 details and in the summary it shows 'zero' in all the fields.

After adding details , click on "Save" and then refresh after 10 minutes.

Doubting the same, I went through my earlier month's (July'17) final summary (which I did by using offline tool and uploaded) -- there also it is showing a lesser value only.  i.e., the final summary figures have not tallied with that of my billing program/invoices.

Kindly, guide me what I should do now?  Shall I proceed as it is?

Thanks.
