Issue with updated featured image

Hi,

I am developing a website for a client using the premium version of the Ultimate CSV Importer Pro.

Import works fine. I have tested an update by changing the featured image from one value (call it A) to a new one (call it B). The update works fine, and displays the correct new image (B) path in the backend. However, in the front end – the site displays the original featured image (A).

The front end layout is calling a predefined custom thumbnail image e.g.
<?php the_post_thumbnail(‘progression-studios-video-index’); ?>

The custom thumbnail is working fine (and displaying in the front end correctly) on the initial import, so I’m wondering if there’s something in the update that is not updating all of the references to the new media asset? As it continues to show the old image. Hope this makes sense and appreciate any help in advance.

Best
