iOS 8.3 Jailbroken iPhone 6

Hello I have jailbroken iPhone 6 on iOS 8.3 by TaiG everything is awesome except one thing I was installing tweaks and after sometime I realised that my music cover on lock screen is gone and I've been searching on Google and YouTube but it look's like that nobody had such a problem yet and I know that is very popular forum and that there are lot of Jailbreak themes so I hope that maybe I will get any answer here
