Change to character sheet shield icon

[Ozsome]

Not exactly sure how to report this but I have been using FG for 2 years pretty heavy.
This past week one of my character's sheets had something I had not seen on the AC icon.
I attached the screen shot of his AC.
His AC is for +2 half plate and a +2 shield.
With max dex +2 (which he has) it should be at 23.
But his is at 28 with a small +5 in the upper right corner.
I have checked all feats, all items, all spells, and the only thing in the combat tracker is his vision.

Could someone help me figure when this +5 started or where I could find more about it?

Thanks for any help in advance.

ctrl+scroll over the field will do that

Clicking the magnifying glass should tell you. Perhaps it was accidentally set up to include a second attribute modifier (WIS); perhaps a flat bonus was applied. Both are doable.

This is what's known as a temporary modifier and as @damned say, you change that using CTRL+mouse-wheel.
