Hi @Squideyes
Your code the_field('download_cv'); is outside of the loop! This is why ACF does not understand where to load the data from.
Where is the data for ‘download_cv’ saved? Is it on the page which you have selected the CV template for?
I think the issue is with all your global $wp_query stuff.
You should use not override this global variable, but use a new variable. Also, make sure you use the reset_postdata function after the loop. This is all documented on the WP site.
Thanks
