CRS overall score went down automatically

[kumarwinningman]

I was created my profile on 6th Jan 2015. when i was created my overall score was 816. After couple of week my overall score went down to 780. i am working in Canada from 2012 onwards That means i already complete more then two years inside Canada. when i created my profile i got 46 mark in Canada work experiences and i got 50 in skill transferability -foreign work experiences . But after couple of week my Canada work experiences went down to 35 mark and skill transferability -foreign work experiences went down to 25 mark. can you please guide me to correct this mistake. Thank you
