Hello! I'm not sure if this is a UCP problem or if it was already there, but we have tried to add several galleries on the same page and it turns out that if they all contain the same image (we use an "Empty Gallery" picture for these situations) and try later to add an image to only one of them, this one is added in all the galleries that are using the same photos, in this case those with the "Empty Gallery" image in them.

We have already thought about a solution for this in our wiki, but I comment this so that you can fix it for the others in the future.
