Thank you, but there are no 'more actions' button. That was the first thing I tried. All of the albums that I want to keep have them, but the empty, duplicate albums do not. I have even tried adding photos into them to see if it would then give me the option to delete, but it said to choose a destination folder. Photo adder dose not recognize them.
For an album that was published from Family Tree Builder, in order to delete it, please go to Photos and Videos > Find, and there you will see a list of your albums, and you will see the delete option.
