I know there was a thread on this before and I don't remember seeing a fix for it as far as getting rid of profiles you accidently activate. It was really just an annoyance I don't think it causes any problems but when I sbf'd and they were still there I figured they had to be on the sd card.

So using ES explorer, first you have to go into settings and file settings and scroll down to the bottom and check show hidden files. Then on the sd card go to the Android folder then data then com.motorola.blur.home then click files and finally profiles. Then all you have to do is just long press and delete the profile and background you don't want and you are good to go.

Sorry if this has already been discussed before I just don't remember seeing it so thought I would put it up here in case it bothered others as it did me.
