Why Is There A Lock Icon On My Fader In The Fader Config Tab?

Issue

In Tab 36 (Fader Config) I see my fader has a lock icon next to the word Load. Does this mean I cannot change the configuration of my fader?

The lock appearing next to Load indicates that only the Load button can not be reassigned to a different function.

You can continue to map new functions to the bump buttons and fader below, however.
