Limit on watch faces

I am curious as to why, when I download any watch faces, I can only save 10 of them to my watch. When I go to download more, some watch faces are removed from my recents on my watch. Is there a reason why all of my facer watch faces are not being stored on my watch?

Facer limits it to 10 for free users. If you pay the one time fee to get rid of advertisements in the app it goes up to 20. The only way to “keep” them is to like the watch face that way you will be able to find it again if it drops out of the watch box.
