What do you do for background checks when a company you were in no longer exists?

The background check companies aren't giving you like a pass fail and instead there are simply checking from outside sources if the information that you provided on the background check lines up with those sources. And any differences are flagged her review. So if a company doesn't exist anymore, your side of the form will say information about the company and their side will say like unable to contact, or company does not exist. And most likely anyone looking at their final report will just ignore that if it seems legitimate. I did a background check where the company like filled out their side in correctly and like they put the wrong job title and listed it under the salary field and that was like flagged as a difference but no one cared. I was doing a background check for Facebook and I had done an internship in the past on Facebook in the background check company couldn't verify that I had done that internship and also flag that which was kind of funny.
