Bug report: demotion

It has always been that you need to lose ATLEAST 3 games on 0 LP to be demoted to a lower division, however, for past few months I've been demoted when losing only 2 games at 0LP. Ultimately, today I got demoted after losing 1 game at 0 LP. Can this bug please get some attention? If anyone wonders, my MMR is fine, not too low for my division.
