According to The Telegraph, the Duke and Duchess of Sussex formerly sat close to the top alongside Prince William and Princess Catherine.
Markle is second to last, sitting only above Prince Andrew, who stepped back from public life in the wake of the Jeffery Epstein sex trafficking scandal.
The website 'demotion' comes just over a year after Prince Harry and Markle dropped down the rankings on the royal website. They moved from just underneath the then-Duke and Duchess of Cambridge to underneath the Wessexes and Princess Anne as tensions bubbled under the surface following Megxit.
The new titles for Prince Harry's children are thanks to rules set out by King George V in 1917.
Technically, as Archie and Lili are now the children of a son of a sovereign, the two little ones can now use the titles of Prince and Princess.
A spokesman for the Palace told the Express in mid-September that the titles will be updated on the website 'as and when we get information'.
It has not been confirmed yet by their parents or Buckingham Palace whether the children will use the titles, although they now are technically a Prince and Princess.
The King has expressed his love for Harry, Meghan, and their children, with a palace spokesperson highlighting to the Express that all titles will be updated as they are announced.
In 2021, it was suggested Charles - in a bid to limit the number of key royals - intended to prevent Archie from becoming a Prince when he became the Monarch.
King Charles said last May that when he ascended the throne he intended to have a 'slimmed down' monarchy, which hinted that he could change key legal documents and therefore prevent Archie and Lilibet from receiving their Prince and Princess titles.
