full width not working on homepage

Hi, i had a 100% wide slider on the homepage for weeks with no issue, I made no updates or changes of any kind to the homepage but now the slider is not 100% wide but about 80% and left aligned. Whats weirder is that ive made a duplicate of the homepage at muddyadventures.es/sandbox and the slider is 100%, AND to get even weirder again if you click to inspect on the homepage it makes the slider 100% until you refresh the page…I have tried making various sliders and still the same thing happens…please help im so confused!
