If you're referring to the tooltips (in the patch notes 8.24b):

"Known Bug - In-game tooltips won’t reflect the change but it’s just the tooltips! Rest assured, your heals and shields will be larger!"

The tooltips aren't updated because it's a balance patch, and that's how Riot handle balanced patches: they modify the game slightly but do not update tooltip until the new "big" patch (which is going to be patch 9.1 here)
