The scale is not tested and this can causes a bug in some cases when we try to remove an axis inside the same input name with different scales but with the same key.
All axis with the same key are removed no matter what the axis scale is when we send the InputAxisMapping struct to the method.
When I remove a key mapping with the same axis name and the same key but differents scales (MoveForward = Positive axis scale 1 .0 / MoveBackward = Negative axis scale -1.0) it doesn’t work as it should.
When I look in the engine source code in the method RemoveAxisMapping I see that the if condition is missing “KeyMapping.Scale == InKeyMapping.Scale”.
Steps to reproduce :
Create a new project
Create a PlayerController set it as default player controller in gamemode
Create 1 Axis Mapping and inside it create 2 entries with the same key but differents scales in input settings
Bind a key to RemoveAxisMapping and create an InputKeyMappingAxis struct with the data of one of the two keys created in input settings in the player controller
Launch the project and press the key
Close the project and look at the input settings, all of the keys with the same key are removed no matter what is the scale.
