Slider offset on initial loadup on desktop.

I have a wordpress site using the Huntor Theme, and since a few updates ago, the slider on the home page loads offset to the left, when one resizes the window and expands to full screen, the slider is positioned correctly.

you can see here on overlandgcc.com the issue, just resize the window, and then expanding again to centre the slider

I have linked a video to the issue here https://youtu.be/dev16vzzR6w

What could be the issue.
