Slider Revolution Full width problem

Slider Revolution Full width
When I load the start page, the slider is first small and then suddenly full width. What do I have to set, that the slider is already at the beginning on full width? Example: https://jamb-xxl.ch/test/

Where can I get the Woodmart templates from Slider Revolution, these ones where they are on the demo site? https://woodmart.xtemos.com/

Many thanks for your help.
