Gallery Mulitply?

for the past week, I have been having issues with the Gallery because everytime I open my  profile to see the builds I have uploaded, it's there 3 or 4 times and I've only uploaded it once, but also when I am building a house or room's that when I go save it, it says that I have used Custom Content, but I haven't used any sort of CC on the build, I do use CC but everyhting is up to date, and for me to even upload the stuff I have to save my game disable mods and close the game, reopen it and then upload thing's that way, before then I have to re enable my mods and then restarting the game.
