Adding custom themes and lockscreens

[Charger24s]

I am new to jailbreaking and just jailbroke my iPhone 4 with the new greenposion rc5. my question is why don't some of the lockscreens that come with the custom themes load. Any help would be great. thank you

Happening to lots of people After using greenpoison. I use illumine theme and no lock-screen theme shows even if I prioritise it in winterboard.
