Problem with new Photos App sharing for screensaver

Not sure how to word the title here, but ever since iPhoto went away and it's not just Photos, I have problems with my Apple TV pulling the right photos from my Mac. I have gone into iTunes Home Sharing, and tried everything. If I share only the one album I want to pull from for the screensaver, it ignores it and pulls from all photos. And when I go into the screen saver settings in Apple TV, I have no options to choose from various albums like I used to when it was iPhoto. Any ideas??
