wp_reset_postdata not working

I have a WP_Query for a few posts echoing some images attached to them from a category. I reset the post data and it still seems to be affecting the main loop on the same page on my live site. Developing locally its not affected. I have read the codex and believe I have followed best practice for reseting the post data, but I could have made a mistake!

Thank you
