Thanks for contacting us, I have checked your website, and your non-AMP category page version has some problems. I would suggest checking first how to solve those issues.
1. You have a few plugins that are doing almost the same thing and it could cause conflicts:
– LiteSpeed Cache
– Page Optimize
– Jetpack Boost
Check if they are not overdoing tasks, there is an error on the minified javaScript it can block the rendering for your page:
– Polylang
– Lingotek Translation
– Polylang Connect for Elementor – Templates Translation & Language Switcher
Two plugins for language, I suggest checking if they are not affecting the archive structure. The Polylang for Elementor is needed if you are not using the elementor?
2. Related to AMP
You are using two compatible AMP themes, TwentyTwelve for your non-AMP version and twenty twenty-one for the AMP version, you can use transitional mode and only use one theme.
In meantime, you can disable AMP for the category page, until you solve those issues.
