Ok, I downloaded v20 and it looks like the component you're referring to is called this:
~Sensible weapon restrictions for SoA (non-mod weapons)~
Did you only get ~sensible~ displayed onscreen, or the whole thing? If the former, it's a bug.
Note that although it says Universal rather than Sensible in the component name, looking at Ghrey's code it seems to be almost Universal.
Regarding Keldorn's proficiencies:
~SoA Keldorn's new proficiencies (Crossbow, Flail, Single-weapon Style, Scimitar, and Short Sword)]
~SoA Viconia's new proficiencies (Crossbow, Flail, Single-weapon Style, Scimitar, and Short Sword)]
[Requires Universal Items for SoA~
You are correct, they do indeed appear to be the same.
It seems intentional, though why Ghrey removed Keldorn's Two - Handed Sword proficiency I don't know.
The NPC proficiency changes are doing a file check for BOLA01.ITM in the Override which is added by the earlier component (except Keldorn's, which isn't checking for any file). Except the Sensible Weapons component isn't the one adding them, instead it is the Unique Weapons component.
So, for now either install Unique Weapons too, else copy something to a dummy file called BOLA01.ITM and it should let you install the other component.s
