Again, this looks like a combination of css and custom template. As I am unfamiliar with anything you have edited in your custom template, I can't advise further.

It's not coming from the CSS.
I disabled the CSS (both from global and override) and the half-bold problem still occured.
Problem fixed.
I accidentally removed the content of this directory:
/includes/templates/YOURTEMPLATE/templates/tpl_modules_product_listing.php
This file is created by the Column Layout Grid add-on.
... and 2 years later you've solved my problem! Many thanks ...
