Is anyone having a problem after the recent Alex update on Minecraft- Xbox One edition?

I play Minecraft with my daughters and the game worked perfectly until the recent Alex update. Ever since the update, the monsters act erratically, skeletons jump 30ft in the air, zombies run super fast, and spiders phase in and out. This also makes them unable to target and attack. The livestock is phasing thru the walls, and the pet dogs fly around as if in a scene from Twister. I uninstalled the game and deleted the saved games but the problem persists. Is anyone else having a problem or how do I fix it?
