Moving Faders - Unexpected Outcome with Erroneous typing

Noticed some unexpected outcomes when moving faders and fat fingering.  Original plan was Fader 1/5 thru 6 move to 51/5 enter.

What I actually typed - Syntax Fader 1/5 thru 6 move to 51 enter (fat fingered enter without the /5) the faders moved 6/1, which was not what I would have expected, I expected a syntax error or maybe fader 51 (5/1) When recreating this outcome to post, I also tried entering Fader 1/5 thru 6 move to 51/ and Fader 1/6 moved to 1/1 and 1/5 did nothing.

First noticed this on an Apex on 3.3.5, recreated on Mac 3.3.6
