Default Suddenly my internal is write protected

Been flashing roms for years. i use Omega rom on my Galaxy Note 3. When i flashed the latest rom, my internal SD card is all of a sudden write protected and i can't change it. i doubt it is a rom problem, which is why i am posting it here. None of my apps can save info.

The only difference this time i flashed is that i did a full wipe. Maybe i had this problem before but don't remember....

i have searched and i have found other people with this problem... but the solutions i did find were just... weird and didn't work or pertain to my phone.

Also, under permissions it is RWXRWX, which doesnt sound write protected to me.

EDIT: Figured out the problem, but not the solution. For some really odd reason, dropbox screwed up the folders when syncing using dropsync. Still have no idea hy this happened and how to fix it as i cannot delete the folders it created/sync'd

EDIT 2: Everything fixed accept six axis folder in sdcard/data. it cannot be deleted, renamed, or have anything added to it
