A problem on lists that I made but didn't edited

Hey, I have been having this problem and it's my IMDb lists that said they were edited but I did not edited it. This one is My so far Dream Crew and Cast for an animated Inspector Gadget movie is the new one. Also I think I might now know what this problem is, the people or titles in my lists might of had their IMDb pages updated with edits by other IMDb users which might be the reason why the list was updated without me. If that is so, can you observe who got an edited update on my IMDb list "My so far Dream Crew and Cast for an animated Inspector Gadget movie" please? If it's not that, then I guess I have to change my IMDb password again.
