Can't change static background image on Efor Coaching "Linda" theme

I purchased the Efor themeforest “Linda” for coaching businesses. There is a background image of a woman and man that remains as the sliders go over it I want to change that image. Does anyone know how to do it? There is no “background” image option I can find anywhere on Elemenator or Customization. Thanks for any help!
