why is my character moving even when no input is given?

Hi,

In the INPUT section of the PROJECT SETTINGS, I’ve added “Generic USB Controller” Axis mapping to the movement controls “MoveForward” and “MoveRight” in order to move my character using a Logitech GamePad. The keyboard key assignment is W,A,S,D for this function.

When I start my game now, somehow the character starts moving forward without me doing anything. Does anybody know what’s going on here? It seems to me that the Logitech GamePad is somehow not at an input value of zero when not in use.

THX!
