If you have certified proof of cancellation, that should be enough proof for the title company to remove the liens. I would suggest calling the title company, and sending them the documantation that you have. If they are able to review the documentation, and determine that they are in fact satisfied by calling and confirming with the clerk's office, you could be okay to proceed. It isn't the fact that they are showing up on the credit report, becuase a mortgage underwriter would accept a "credit supplement" to the credit report confirming that they liens are paid. It is the fact that the title is not yet cleared. The title company is who you can look to for any help possible. It may be that they still need to wait, I am not sure without seeing the actual documentation you have, nor do I know if the Clerk's office will be able to confirm, but that is your best bet for closing now.
