I don't think it's normal.
I would confirm this from another source before tinkering, but this is
my understanding:
The rubber skirt around the knob will come off if you get under it with
something thin and pry it.
Under the rubber, there is a hole in the knob that will take a metric
hex key (Allen wrench).
Maybe this has gotten loose.
