Remove 'empty' event folder - iPhoto 5.1

[RolledUp20s]

Ive given iphoto a go on the ipad 2....(this shouldve been free with 5.1 but nevermind) anyway, ive synced iphoto from mac with my ipad, just going through some old events, deleting photos & ive come across this..
When the photos are deleted from the folder, the folder remains...along with the keyphoto...damn annoying. Why cant i delete the folder from the ipad??
...or, how?

I'm pretty sure you cannot delete photos in iPhoto, only hide them with the "x" button. You'll have to unsync the event with iTunes in order to get rid of it entirely.
