Chrome suggests nsfw/gore subreddits that i never visited and don't show up when doing an internet history search

Good evening,

Today I was going to visit the r/pugs subreddit when i noticed that when i wrote "/r/p" a lot of gore subreddits were suggested (dead children, as example). Thought it was some sort of spyware, so I checked the internet history and nope, nothing there. Also thought it was a joke subreddit or something like that, but no, it was several pictures of gruesome content.

Why does this happen?

Also, i tried openning an "incognito mode" window and those results didn't show up.

Tried abling and disabling the "i'm +18" feature, and it continues to show up.

Thanks for your time.

No, in this computer there's no RES, all on default.
