Item Sets Map Option

It says Summoners Rift(Beta) when you press play and select Summoners Rift in the middle of the screen. And also when you open up the Item Sets tab and click on Maps and Champions, Summoners Rift is named as "Summoners Rift(Beta)" even though in Patch 5.5 notes it clearly says Summoners Rift isn't in beta anymore.

Guess Riot Games forgot to change it there? Or am I wrong?
