[Client] The Gold League That I Am In Has A Buggy Name

For me in the client it says I am in Gold Division V Vladimir's Barracudas but for other websites and for my friends it says I am in Vladimir's Bandits. It used to say Vladimir's Bandits for me as well but it changed recently. Is it even possible for the names of leagues to change? I just found this weird and it cause a huge argument among my friends and I over the name of our league.
