What's the point of personalisation if Vinted is showing me all kinds of sizes??

I just don't get it. I have a certain size set in my personalisation and then I made a mistake of favouriting something that was one size larger - boom, my entire front page is now that size or larger. I've deleted anything that was that size off my favourites and reset my personalisation but vinted doesn't give a shite. So now I get cool clothes recommendations that are way too big in sizing OR BETTER YET, random children clothing. Fantastic algorithm, very helpful, thanks.
