Immediate demotion after being moved to S4

Hi, I was S5 at the end of the season and immediately before 8.24 hit I had a few wins and got to 84LP. When 8.24 landed I was promoted to S4, so far so good... I lost a game last night and it didn't seem to affect my LP at all but today when I log in I am in bronze 1!!! Why have I been demoted for losing a single game when I had 5 wins in a row before this??? You can check my match history here: [Match History]( Please tell me this is not how new ranked is meant to work?!! Fanconi {{sticker:zombie-brand-facepalm}}
