"Mineplex" SERVER shows glitchy green writing

While on the "Servers" tab from clicking "Play" in the start-up menu, the server "Mineplex - EU > UPDATED SKYWARS" has some glitchy green text next to it, I'm not sure if it's meant to be there but on closer inspection of taking a few screenshots, these letters are just literal jibberish.

Showing a screenshot doesn't justify what it looks like, it changes the letters super quickly so you can't actually see what it's saying without taking a screenshot.
