I paid off a creditor that had a judgment on me and they will not report it to the court that issued the judgment, paid in full

Hello I am a Washington state resident, I was in a motorcycle accident awhile back and was behind on rent. It went to superior court and the landlord was granted a $1000.00 judgment against me, after I was able to return to work, I set up a payment plan with the landlords property manager with a letter that she would agree to notify the court that the judgment was paid, well it was paid and the property manager now tells me she cant write the letter only the owner can, and the property manager will not release the owners information to me, I even gave them a form the court needs to release the judgment and they still will not send it in. I contacted the court about this and they said they can’t do anything until they receive a sign letter from the owner that the judgment is paid in full.
