Adding a QI Focus to a character

[lordmaxx]

I have a character who is locked from new creation. He's a brawling adept with Critical Strike 4. He wants to buy a Qi Focus for Critical strike to add 2 more to it.

Now if this were character creation mode... If I add a Qi Focus and select critical strike I'm able to select unarmed combat as is correct and his Critical strike shows 4/6

But the character is locked from character creation and the drop down is no longer there it just says -Choose- in text next to Critical strike and does not allow me to choose Unarmed combat so it doesn't actually increase that power. Also if I just activate it and go into advancements and just up the power by 2 that just throws in all sorts of validation errors.

Am I missing something?
