League Displays removing my own wallpaper

Hi, I have League displays and its a great little app. I love the screensavers but i am now having problems with my own selected wallpaper. Even if i do not add any wallpapers to the wallpapaer section, when i restart my computer the app removes my own wallpaper i have set. (not a wallpaper from the League displays app)

There is no settings i can see to disable the app from changing the wallpaper. Can anyone help with this because i do really like the screen saver part of the app.
