Not sure if this is to do with the recent update bugs, but here goes. Sorry if this has been reported already, I don't usually check here very often.
So, since yesterday, every time I log on, I get "Dogecake has just unlocked the Actress Mouse title". I'm 100% sure I had this title unlocked ages ago, and it's kinda annoying when I log on, to keep changing it back to "herp derp". I'm on a Chromebook, browsers Chrome OS.

That happened to me a couple days ago, but only once. It was "Actress Mouse*" though. Thought I was the only one.

Weird. Have you tried leaving the Actress mouse title on and logging off and back on again instead of changing it right away?

Actually mine was the title «Sexy» with one star added
