@Sala Iโve spent some time this morning reviewing your WordPress configuration. The issue of the duplicated h1 tag is being caused by AnsPress - youโll no doubt recall I warned against using this โpluginโ (if you can call it that - itโs terrible) here

AnsPress is well-known in WordPress circles for being one of those plugins youโd avoid at all costs. I used it once - never again. It causes far too many issues, and provided you donโt mind your site suffering as a result in terms of performance, bugs, and the like, then ok. In relation to SEO, see the below

This was reported in October 2022, and itโs still not fixed.
From my own independent review, I also see the following issues

The most damaging of these is content being served on both non-www and www URLS, which needs to be fixed ASAP. Youโll note that the h1 heading appears twice (which youโre already aware of)

However, aside from SEO, I see far more important issues that you need to resolve first
TTFB (Time to First Byte) - the page is incredibly slow to load - in some cases, it takes 2-3 seconds before any content is shown. This is a killer in itself as more than one second loading time is considered far too high.
301 redirects are missing - in this case, you should have a global redirect so that the content is being served from the same domain at all times.
The bottom line here, and the โfixโ is to remove AnsPress. Clearly, this isnโt palatable from your perspective as there is significant investment on your side. I know from previous discussions that AnsPress was shipped with the theme you are using, but itโs a below-par plugin in terms of performance and stability.
Youโll see below my attempts to get AnsPress working as far back as 2017 - I promptly gave up, because it was such a mess

And finally, one very well respected WordPress resource (wpcrafter.com) parted ways with AnsPress in 2018 for similar reasons, which he clearly stated

At this point, I would weigh up the investment in AnsPress and seriously consider removing it.
