Common UI Slider - Pressing A Button reset slider value

Yeah, I’ve tried to put it on the right. And when I’ve clicked on it, the slider went to the left, as closest as possible to the screen center.
This problem is really comming from the Analog Controller.
I wasn’t able to work in it since the last time I’ve posted here, but I’ll probably try to catch all of the inputs and edit the slider in code by myself.
