You accepted the nomination in GICS? Not sure what could be the reason for the points not reflecting. In my case, I received a message in GICS soon after accepting the nomination.
"You have accepted a nomination from SK.
Congratulations! You have accepted a nomination from SK under their Provincial Nominee Program. By accepting this nomination, you agree to abide by the requirements of this provincial program, including the intention to reside in SK.
Because you have accepted a provincial/territorial nomination you have been allotted an additional 600 points in the Express Entry Comprehensive Ranking System and it is likely that you will be issued an invitation to apply for permanent residence."
