Problem with custom Battery setting in MyDell App

So I am trying to create a custom power setting that my charging should begin when battery level is 10% and it should stop when it is above 95%.

MyDell Application have this option as given in below screenshot. However, when I try to move the slider for Start Charging to 10%, it defaults back to 50% by itself. The slider for stop charging works when I move it to 95%.

Anyone faced this issue?
