[Q] P3110(samsung Galaxy Tab 2 7.0 [Wi-fi]) Cm11 Storage problem topic

Hello, I have owned my Samsung Galaxy Tab 2 for some time, and i rooted with the belief that the stock OS for the tablet is out of date. And the new root using twrp Recovery and CM11 as the rom was working brilliantly compared to the previous OS installed. But when i tried getting all my previous apps on the device, the device prompted me when downloading saying that internal storage has insufficient storage for the application. So i checked the Storage settings in the settings app, and I have 456mb available out of the 4.59GB that is supposed to be available! I don't know what to do, I have thought it through for a while and nothing came to mind. If you could help that would be greatly appreciated. Thank you. :p
