We're told the reason it took so long is that Kylie was super chill about the situation ... but somebody else in the family wasn't. Our sources say that the person -- we're not allowed to say who -- recently noticed Jordyn's stuff was still there and thought it was ridiculous and disrespectful ... like she was using Kylie's pad for storage.
Kylie decided to get Jordyn to get her stuff out quickly after that ... to keep the peace in her fam.
We're told Kylie wasn't home when Jordyn came over, but the housekeeper let her in and there were no issues. As we've told you, the 2 have remained amicable throughout the ordeal even though they're not as close as they used to be. Our sources say they still text each other on occasion, as well.
