Just a quick look at how mine is and yours seems the same:

And inside the scripts folder:

When you run the minetweaker reload command (in game) does it come up with an error message (make sure you have the scripts installed on your client to see this, even though other players won't need this)
And did you try removing the configs, because here is my configs folder:
http://puu.sh/bDcfG.png
Obviously there is more below it, just showing I don't have any configs, which may conflict
