Mob Spawner not deactivating survival amongst other things

Last night i logged on to update to 1.11.0 , no issues. Today after fighting to log into my Microsoft account ( which is frequent ugh ) I proceeded to go to a skeleton spawner I found and turned into a farm. It was deactivated but now ..... i can't seem to deactivate it. Does the old method of torches on all sides not work anymore or is this a bug. Other than the mob spawner,  the annoying log in issues ( wish i could stay logged in but yea don't work for me)  and the crazy drops in frames the game is still good , keep up the great work Mojang
