Not able to file gstr-4 offline

I got registered on GST on 22-11-2017 While preparing GSTR-4 offline in excel sheet for the quarter 3 (oct-dec) facing an error. The error is that in tax period column there is no option to select oct-dec. It always shows July-September. 

I tried downloading new or updated versions of GST portal but no use.

And did I need to file Nill return if the problem continues in any other way to sort it out
