Fasting a Kaffarah for breaking a vow

[islamion]

Back in my teenage days I used to say "Wallahi" a lot, and sometimes I perchance happened to make a vow with the use of Allah's name but I broke it. I know the Kaffarah is three days.. I have altogether 24 fasts to make. I was wondering what happens when I break a kaffarah fast? Moreover Im making up 6 of these fasts during Shawwal with the intention of getting the reward for the 6 days of "sunnah fasting" as well..

I guess all the ulema must be in Jamaat (Husn e Zan) Hehe

I am waiting for the opinion of a scholar (no offense), I am pretty sure I have to fast only one day... however I am not sure if the intention changes to a fardh fast.. If so, then am I allowed to make the intention for kaffarah of my vows.. or do I make (lol) kaffarah for my kaffarah fast and then fast another 24 days..? (hence this kaffarah for my kaffarah will not be included as a kaffarh for my vow)

lolz, It is just that I was under the impression that for example if someone were to pray nafl salaah and then break it, it is fardh upon that person to make up that salaah.. am I right?
Is that not the case with a "nafl" fast?
