Why can't my published series of novels be displayed under the "Novels" section on the main menu of the website, but can only be found under "Community - Novels"? Is it because I have too few subscribers?
The "Novels" section is only for publishing houses that have contracts with Tapas I believe. Everything self published goes in the community tab. You could have 10 or 10,000 subs, without a contract you're not getting on that tab.
Front page and novels tab of the main page is for Premium only (authors with contracts) and a few Early Access novels. Otherwise, your novel will appear in the Community tab.
