I was adding a a feat that gives investigation proficiency, but when I added it to the character the proficiency didn't reflect on the sheet. I tried adding other proficiencies and they worked fine but not Investigation. Sheet in Question

Your Investigation number is blue instead of black. That means it has been specifically edited to display a “1.” If you remove that customization, does it work then?

It's blue because I customized it to have proficiency, giving it a +3 like it is supposed to be.  If I turn that off it goes back to just her Int modifier of +1.

Is it a homebrewed feat?
