Some of my ELO points disappeared

Basically what the title says. When I reached 1501 there seemed to be a glitch/bug where displayed my score as 1495 (in the stats sections, but at first it said I was still 1501 in the play menu) but I thought this was just the site being slow or something like that. The next day I checked my score again, but it had remained 1495 (this time it displayed 1495 both in stats and play). As you can see in this picture, I should have only lost 9-10 points but instead I lost 15. Any help figuring out why this happened would be appreciated

Rating points don't always go up and down by a stable number of points.

One of the factors is the difference in ratings before the game.

Beating someone rated more than 100 points below you only earned you 6 points while you lost 15 points for losing to someone rated close to your rating.

I know but when I was playing the game it did not display -15 if I lost, and when I was playing the game it displayed my score as 1495, when it should have been 1501

Also, I do not really understand why I would suddenly lose 15 points, usually I would only lose 9 points to someone rated around 40 points lower than me. I know that sometimes you win/lose a larger amount of points, but I thought this only happened after you were inactive in that time control for a while
