Custom query images not displaying in lightbox

I’m trying to create portofolio layouts that are based on categories i set with the Enhanced Media Library plugin. I’ve made a custom query that i entered in the post based content source option.

This does load my images, and they show up in the layout. However, when i click on them, i get a black lightbox, but no image.

$args = array(
‘post_type’ => ‘attachment’,
‘post_mime_type’ =>’image’,
‘post_status’ => ‘inherit’,
‘posts_per_page’ => -1,
‘tax_query’ => array(
array(
‘taxonomy’ => ‘media_category’,
‘field’ => ‘slug’,
‘terms’ => ‘featured’
)
)
);

this translates into: post_type=attachment&post_mime_type=image&post_status=inherit&posts_per_page=-1&tax_query[0][taxonomy]=media_category&tax_query[0][field]=slug&tax_query[0][terms]=featured

I do see that the links on the gallery here are of the form:
https://127.0.0.1/wordpress/_ame5898/
while those from other image content source based ones are of the form:
https://127.0.0.1/wordpress/wp-content/uploads/2019/01/AME4750-1280×1920.jpg

any suggestions to what i’m doing wrong?

Thanks!!
