That screen is all kinds of faulty with conditional modifiers. Try to get targeted by a CON save spell, and then see what the roll looks like.
I don't know how you come to that conclusion. The combination of CON 14 and CHA 16 alone should give a +5 Bonus to CON saves even if the item mods were conditional, but from what my research tells me those mods are static too. This should be a static +7 to CON saves plain and simple.
