Not sure if 6.0.3 would change anything because it's a new and not stable version yet but if you want, we can send it to you. But please send us request about new Layer Slider version thru contact form on the right at https://themeforest.net/user/muffingroup#contact
To be honest, we don't know why it does not work because we do not use Layer Slider as in our opinion it's weak and is not so good as Revolution Slider. We definitely recommend to use Revolution because it's much better.
