Sometimes when you buy the next skill in a progression, the previous skill is no longer shown on the character.
For example, Adept Bookcaster "supersedes" Novice Bookcaster.
In many cases I suggest that you keep showing the lower skill on the character sheet, to avoid the appearance that (in this case) you don't have the skill to Bookcast Novice spells.
Alternatively, the rules could be adjusted so that the higher skill (Adept Bookcaster) explicitly includes the lower:
"The character can now cast both Novice and Adept level spells directly from their spellbook. Although the spell will still exhaust the associated Spell-Slot..." (bold indicates the change in wording.
I would make a similar argument to continue showing Short Weapons even after purchasing Long Weapons.
Probably (not positive) this goes for anything that isn't the exact same skill name, followed by ranks. Meaning, it isn't needed for Prospect II.
