Your sheet is private, it needs to be set to public for us to see it. But if you're talking about in the Hit/DC column it says WIS [number] that's what type of save the target has to make, it isn't saying the DC is based on WIS. The type of save is determined by the spell, not the caster's class.
I just made a bard but the Hit/Dc on my Spells says WIS not CHA. I double checked and they are bard spells.
