Empty category won't delete itself !!!

Okay, this is weird. I recently decided to delete a category from my gallery. I first hid all the cels. I then realized that even if the cels were all hidden, the category still remained seen. I then deleted all the cels in it and emptied the trash. Then tried to delete the category. It still shows on my gallery ! But it's not in my manage artwork page anymore.

Please help me get rid of that useless category. It's named "empty" on my main page. Thanks ^_^ !

Manually deleted. If anyone else is having this problem please let me know and I'll vaporize it for you.

Sorry for posting late, my pc's broke so no internet access really ;_;.

Anyway, just wanted to say : thank you so much ^_^. That category was bugging me for a while ! And now it's finally vaporized. Thanks !
