That is an invention of Internet "fake news" websites that invent a new thing every day, please, stop repeating them without foundation.
It was King Juan Carlos who established who and who is not part of the Royal Family, and the king's sisters are not part of it. Pilar and Margarita were never part of the Royal Family, as now Elena and Cristina are not part of it. That is the law. They were educated and growing knowing that they should develop their lives apart from the Crown, and that when their brother was King they would no longer be part of it... therefore they have no right to claim an official presence.
Elena has a job achieved thanks to the influence of her father where she earns a salary more than generous, her parents use their official and private agenda to publicize the company for which she works... something that Felipe continues to allow even though it collides with some of the rules that the Royal House has established. She should be happy and keep discreet, and take care of her children that enough scandals generate lately.
