Unable to get custom post meta template to show at the right place on posts

Hello guys,

I'm following this guide to create a custom post meta template to replace the current post meta template on my site: https://docs.generatepress.com/article/block-element-post-meta-template/
It's worth mentioning that I followed the exact same guide to create a post date template on another website and it worked well. However, on this specific website, it doesn't.
The issue is that the template shows at the wrong location - I set it to replace my current default primary post meta and to appear after the article title.
However, the post meta date appears way above that location, and it doesn't replace my current post meta.
See screenshot here: https://paste.pics/G438H

Thanks in advance for your help.

Regards,

Asen
