Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
It seems you have created a subdomain and Google has decided to show that subdomain because it considers being related to the search intentions, sadly there is no way to force Google to show your main domain over your subdomain, your only option would be adding a redirection to the subdomain so all visitors go from content.club420.com to club420.com but keep in mind that in the link that you shared with us from tymber.io, they need the subdomain “content”, I advise you to get in touch with Tymber support and ask them these questions.

I understand that finding your website under a different name can be very frustrating to you but keep in mind that Google does that very commonly. Even when everything is fine, Google may choose to display a different meta title for your search query result. Google may skip the custom meta data you have set and instead display something from the page’s content that better matches the search intent.
Here are some resources you can read about this specific issue:
