Lol Nexus statistics

After reaching my goal of having more wins than loses, since the reset of season 6, my win number's been reseted but not my loses. So instead of being 440-436, im no 8-436. Plus, since i was bronze 4 and had 8 wins over 2 loses, i end up back to br 5. I do think something doesn't quite fit in the statistics. What do you think?
