Boost LG Tribute storage issues

A

AC Question

I just got an LG Tribute for boost. It is telling me that it is using 1.95 GB of internal storage for System data which came after it did an update to 4.4.2 . It also gave me a notice to system update a file that is 74mb in size but when I try to download it I get the insufficent storage space but phone says I still have 275MB internal storage and 3.5 GB sd storage. I did root the phone to try and clean boost bloatware but on stock rom. I used King root. Any idea why it says the system is using almost 2GB of internal storage?.
