Load size knob question

Load size knob question

I recently bought a 90 series washer and replaced my 70. Is the load size knob suppose to make distinctive clicks at each position? All the other buttons do and they all did on my 70 series. Not sure if this was by design to simulate a 'custom' option for in-between sizes. If that's not the case, any input on how to fix? I imagine it's just stripped if anything.
