Weird unknown problem with classicdock from cydia

[Zheng Xinxin]

I installed classicdock and enabled it for my ios 7 however it still has the gray background similar to ios 7 even though the reflection is there. It's not supposed to be like that, I believe? I even uninstalled and reinstalled again, but it's still the same problem. Can someone kindly help me? Thanks!
