DL3 Stock content changed.

I am using 4 DL3's. Everything was working fine until I went on vacation and had someone fill in for me. Now that I am back i noticed that the person who filled in for me somehow changed all of the DMX addresses on the stock content on one of the DL3's. Due to this 1 of 4 fixtures does not match up and is a total mess. Is there anyway to get all of it back to matching the other DL3's? I am unable to clone stock content like the user content.
Thank you for any help.
