Unfortunately, the problem is still there.
I have deleted the cache in the WordPress installation (via WP Rocket).
The cache in the browser is deleted. The problem is also there in private mode. I have also installed a second browser – the same problem.
The prices on the main store page are sometimes displayed. If I then reload the page, the prices are gone there as desired.
It looks to me that the custom CSS code is not loaded or processed when the page is first loaded.
