Gst 3b issue regarding igst itc settlement

HELLO,

In this month while filling GSTR 3B, the IGST credit first settle with CGST, then CGST against CGST, and SGST against SGST.

because of this I got gst payable in SGST while having credit available in CGST.(this is bacause of IGST credit getting settle against CGST first.)

Can I manually divide IGST equally against CGST and SGST so that I don't have to pay SGST.

I have attached figures for understanding.
