LT Holdings was placed on the lien in error, they are requesting a retraction document immediately or they will go to an attorney. The Levelset researcher found them as the owner, but it was incorrect.
From the description it sounds like an issue that Levelset should be helping you to resolve. If the lien did not name the correct owner and you are past the deadline to file a lien, then you may have lost your lien rights. If you are still within the 90-day window to file a lien, then I would file another lien against the correct owner and also file a release of the lien that named the wrong owner.
