Mobile layout product page issues. Spotlight Theme

[RohanJ95]

 

Happy with my product page layout on desktop view. One large image, with the smaller thumbnails underneath.
However, when I change to mobile view it goes from one large image, to 2 large images side by side, with the same images underneath as thumbnails. I have attached a screenshot of the issue from my mobile.  
I’m wanting to remove the second large image on the right (under the title text), while keeping the two smaller thumbnails underneath. I hope this makes sense. 

Thank you for any help!
