Despite her recent threats,Kim Kardashian West does not have the power to fire one of her sisters fromKeeping Up with the Kardashians,PEOPLE confirms.

OnSunday’s episode,Khloé Kardashianand Kim, 39, fought with Kourtney, 40, for refusing to discuss her romantic relationships on-camera. Eventually, Kim suggested firing Kourtney for having “too many f—ing boundaries.”

However, all three women are executive producers on the popular E! reality show, and multiple sources tell PEOPLE that Kim cannot actually fire Kourtney.

“Kim and Kourtney, just in general, often have issues,” the source adds. “Kim is very influential when it comes to their whole business empire, but she still can’t fire Kourtney.”

Khloé elaborated onthe family’s filming agreementswhile live-tweeting Sunday’s episode.

“We aren’t forcing anybody to film but when you sign a contract you have to hold up your end of your obligations. That’s what sucks. You can’t stop something midway or if you want to there has to be a dialogue about it. Can’t just dip on us,” she wrote.

Later, she explained whyKendall JennerandKylie Jennerappear less frequently than their older sisters do.

“Kendall and Kylie have different contracts,” she wrote. “Kourt, Kim and I have an equal contract.”

In one scene during Sunday’s episode, Khloé and Kim decided to ambush Kourtney at a business meeting, suspecting she was secretly seeing a guy. When they confronted her outside her house, Kourtney was furious.

Kourtney accused her sisters of being “nosy,” which infuriated Kim and Khloé.

“Kourtney spends a lot of time off camera. She won’t talk about her relationship, but you’ll see paparazzi photos of her and her guy that I can’t say his name on the show because Kourtney doesn’t want to,” Kim said. “I’ll see things or read about it online and wonder like, did this really happen? Is she talking to this person? And realize that it’s true, but she’s so secretive with us that she won’t even tell us.”

Kim said that with Kourtney being less open about her life, both she and Khloé have had to “share more.”

“Our job is being open and honest and sharing a lot of ourselves and it just seems like for the past few years now, Kourtney hasn’t really been open about her personal life on camera,” she said. “So all of the days that Kourtney isn’t filming, Khloé and I are picking up the slack and having to share more. Because if we’re not sharing our lives, then what is the show?”

Things came to a head when Kim suggested Kourtney should be fired.

“We have a proposal for you: It starts with an F and ends with a D,” Kim said.

Kim and Khloé also felt that it wasKris Jenner‘s job to intervene.

“As our manager, you should want this show to be successful, you should talk to Kourtney say, ‘Okay, Kourtney, if you’re not willing to bring anything to the table, then you’re done,’” Khloé said.
