Prince Charles' 50 years of work on the Duchy of Cornwall was celebrated on the two-part documentary, "Prince Charles: Inside the Duchy of Cornwall." It focused on how he turned the large property into a cost-effective and innovative production he is extremely proud of.

In the film, the Prince of Wales spoke to farm owners and showed with pride how his protection of organic farming paid off. He also disclosed emotional moments with Prince William who will take over the estate -- likely soon.

According to The Sun, a source said that the documentary is about the Prince's life's work and it really meant a lot to him. However, due to Prince Harry and Meghan Markle's shocking revelation about their struggles and feelings towards their royal duties in their documentary, Prince Charles' documentary was completely ignored.

People are talking about the Sussexes and their controversy while nobody really talked about Prince Charles' accomplishment.

"It's been completely and utterly annihilated, all because these two think they've reinvented the wheel," the Sun source added about Prince Charles' documentary and the Meghan Markle-Prince Harry controversy.

On Friday, at the end of Prince William and Kate Middleton's Pakistan tour, ITV released two clips that boosted the Sussexes' documentary, which sidetracked the attention of many critics.

It was reported that the action has even outshined the Pakistan visit and what it has achieved during their last days.

The royal protocol, though unwritten, requires members of the family not to overshadow official visits undertaken by any senior royals.

According to reports, Prince Charles believes that the conflict between his sons Prince Harry and Prince William is sidetracking from the work he and the rest of the royal family are doing.

Prince Harry's statement that he and his older brother had a falling out has gone down severely with their father, who definitely doesn't want the hullabaloo to overshadow the family.

The father-of-two walked Meghan down the aisle on her wedding day and welcomed her to the family with open arms. Another Sun source said that it's a shame the Duke and Duchess of Sussex didn't go to Balmoral to talk about family things.

There has also been at least one time when the future King of England invited the former "Suits" actress to an event, but didn't show up.

"When the Royal Family send you an invitation, you go. There's no reason why you shouldn't be there," the source added.

Prince Charles is also reportedly worried for his youngest son, the same way he used to fear for Diana. Though he said he will continue to publicly defend Prince Harry, he has become infuriated about the entire situation in private.

Meanwhile, Queen Elizabeth II is reportedly urging her grandsons to sort out their issues privately, although Her Highness remains supportive of them both.
