Anyone Else Noticed This On AI Slider

If I change the AI difficulty setting with the slider from 100% to 90% for example there seems to be no difference when in the game. But if I slide it back to 80% first then go up to 90% they are much slower.

So to get it to work properly I have to slide it back to 80% and then to the new setting, anyone else noticed this? I have the variation setting on 2. V1.14.3.
