Default [Q] double storage after ota update

Hello guys. My internal storage after updating to 4.4.2 kind of duplicated filling my storage faster. Inside emulated folder (The one that is used as SD card or internal storage) i got legacy and 0 folders both with the same files and size (both have 4 gb) and my storage shows that i have only 2gb left. am i the only one with this problem? Anyone knows how to solve it? Thanks. (I attach a screenshot to show the problem)
