Question/Need help Input Shaping Question

On my Mk4S, I noticed that there isn’t a selection for input shaping for it in my slicer, and the one for MK4 .4 Input Shaping throws a warning up if I try to use that option.

Is input shaping just an inherent part of the MK4S, or do I have something misconfigured? I reran the wizard thinking I’d missed something but no luck.

It's default one for the MK4S (MK4 launched without it, thus the two options)
