If you are Refreshing your movies in that set, maybe you want to update your artwork or some other reason, then yes you will remove it from your home-made collection because the movie is rescraped with data from TheMovieDB. TheMovieDB have no idea what collection you have created.
If it is not that, then I have no clue and honestly I would be hard pressed to try and figure it out for you. You could provide a Debug Log which captures an Update Library, and I might spot something related to the issue. Also double check the wiki pages I provided to ensure you are doing it correctly. I have many home-made collections that I have had in my library for many years without any issue. (Alien/Prometheus being one of them)
