M1 V5 Volume knob not working as expected

I just received my new Monsgeek M1 V5 TMR keyboard. When in the monsgeek app I see the volume knob divided into 3 section. The left and right of those sections are obviously for the rotations but the middle section cannot be highlighted or modified in any way. Also when I press the knob there is a obvious click but nothing is happening at all. Is this a hardware issue or a software issue or did I buy a version of the keyboard for which the knob is not a button?
