As i told you before, i dont have my game right now so i cant try to do the same you do to check what is wrong. I am sure that when I used FLU to get Heavy armor feat. it worked for me, If you FLU and then RLU to get heavy armor, it should be available, not light or medium armors, you will only be able to use heavy armors. Continue trying until you get it to work.
I have readed some previous topic of you, where you said you are scoundrel. I have never played with Scoundrels, i have always played with soldiers, i think thats the reason why you are not able to use Armors. Its the only reason i can give you, the only time when i used FLU to get heavy armor feat. it was for bastila and carth and it worked, as you know, carth is a soldier and bastila is a jedi sentinel. I think thats the reason, that you are a scoundrel, so i dont know if it is really possible for you to get heavy amor feat
It's not IMMPOSIBLE for the scoundrel to not get heavy, but its like not possible when FLUING with a scoundrel to get Heavy armor...Ill try to flu bastilla to see if i can get heavy armor for her using the same method...P.S. I FIXED THE GRANTED FEATS crap...I did what you told me to do. IGNORE that. Eventually i got everything I WANTED and I can like RECHOOSE THE FEATS IT said it granted.
im getting my game back this thursday so i will try to see what happen with the heavy armor feat at a FLU, i remember that it worked for bastila and carth, i will let you know
