Possible bug with the intergraded slider


I seem to have run into an issue with the slider on my website which is not functioning correctly when the page is loaded. I managed to find the issue by scaling down the browser window. When you scale it down the slider refreshes and it starts to function the way its intended to. I am not sure if this is a bug or something I have missed but any help on this issue would be greatly appreciated.

I am currently using Google Chrome

Fixed the problem, It had something to do with the container being set to flexbox.
