Married At First Sight fans have spotted another editing fail, after a new promo clip accidentally revealed Billy Vincent's decision to leave wife Susie Bradley at the next commitment ceremony.

On Wednesday, a teaser for Sunday's explosive commitment ceremony showed the 28-year-old holding a 'leave' sign after complaining about his home stay in Byron Bay to the experts.

Billy is seen wearing a blue and white floral shirt and he tells the experts that single mum Susie failed to treat him with any respect during their time together.

Eagle-eye viewers noticed that the same shirt worn by Billy previously appeared in last week's commitment ceremony trailer.

Fans saw four 'leave' signs held up as red filter masked minor details that could identify each person.

One of the minor details that was immediately noticed was the uniquely patterned blue and white shirt worn by Billy in the upcoming commitment ceremony.

The editing inconsistencies expose the barista's decision to leave his marriage this Sunday.

Daily Mail Australia has reached out to Channel Nine for comment.  

So far, season six of Married At First Sight has been marred with a series of editing fails.

On Monday's episode, Susie was the victim of poor editing.

After a fight with 'husband' Billy Vincent, the blonde was filmed going to bed alone in a fitted grey pajama vest top and shorts.

However, the following morning the beauty was filmed waking up in a baggy white branded singlet top. 

As the controversial star was then filmed getting out of bed and walking to the lounge for a confrontation with Billy, her clothing had changed again.

Interestingly, Susie was now wearing a black bikini with vest top - the same outfit she had wore the day before, suggesting the scene was faked. 

Married At First Sight continues on Sunday at 7pm on Channel Nine
