Default [Q] Problem Creating partition in twrp affects sd size

I have a 32 gb micro sd card in my Samsung Fascinate. I attempted to create a partition using twrp recovery, but it failed everytime saying that it could not find the partition. Now when I use my card though it only shows 23.9 gb even though it is completely empty. This was a legit card and it showed the correct amount of gb proir to the failed partition. I don't know why my partition setup failed or why it is now only allowing 23.9 gb.
