Question on Feat

[Freewolf]

So I am creating some new feats.

I plugged in this code to allow the feat to provide proficieny in Investigation, or double proficiency if already proficient.

Interesting thing that happens is when i select the feat it applies double proficiency just fine, but the Investigation with double proficieny now appears twice both in the program and the print out.

Why is that??

doneif (tagis[Helper.ShowSpec] = 0)
doneif (tagis[Helper.Disable] <> 0)

if (hero.tagis[ProfSkill.skInvestig] <> 0) then
       perform hero.assign[ProfDouble.skInvestig]
else
       perform hero.childfound[skInvestig].assign[Helper.Proficient]
endif
