Gallery slideshow navigation arrows

Hi,

I’ve been having issues with the navigation arrows in the gallery slideshows. In the sample page of the theme the arrows and image numbers are aligned and grey. In my webpage the arrows are light blue, the numbers are grey, and everything is overlapping.

I’m not sure how to fix this in the code. Any help is appreciated.

Best,
Sofia
