Get and set game user settings (resolution scale) with slider

Hello
I use a slider to change resolution scale.
Problem is I don’t know why get I other value when I load the getresolutionscaleinformation.
Probably with save procedure are fail or loading procedure but if I want save between 10 and 40 then I get value 41. If I save between value 41 and 100 then I get correct value when I load in.

Loading part:

Slider change value(when I change value then save in float variable):

Finally when click to Save button then save in game user settings:

What is the problem?
I found this tutorial Scalability Reference | Unreal Engine Documentation and it says resolution scale are between 10-100. I don’t understand why the value on 41.148 and/or 42(if I use round) when I want load resolution scale value.

You may want to set your Min Scale Value. I believe this clamps at 40 by default, hence why you are always at 41. That’s likely because of the rounding (40.4 = 41) and the Min setting getting in your way.
