Facebook search bar says I visited profiles/pages I never clicked on or seen?

So recently I saw my husband's Facebook search bar and was not happy with the results.(provocative women) he swears up and down he has never clicked on those profiles or have never even seen them. ( hard for me to believe😒) but after doing research its hard to find much on it. A Reddit thread said the same thing (that it was happening to other people) only about 5 people commented. I want to know if this happened or is this happening to anybody else? Did you truly never click on the profile/page? (I dont want to believe he's lying to me so im looking to see if anyone experienced this also.)
