Nobody said they’re unrelated, first of all - in fact, that arguably makes it worse. Quickly looking it up, I believe capacitance is distinct from charge, which coulombs are a unit of.
But even if they weren’t, the point would be that they use the same character, possibly causing confusion so as to which is being referred to in equation or text when using the symbol.
Ah yes, Coulombs and capacitance, two things that are totally unique and unrelated entries in this list.
