I think that's what the title company was trying to do...clean up the title by getting a QC deed from a previous owner that must have clouded the title with any remaining interest.
Most likely the office that handled the transaction will not be involved at this point because they have a claims division to help with this stuff and those claims divisions have attorneys on staff. They insured your title, so they have no choice but to fix it. That is what title insurance is and why you get it :)
The deed you have probably looks normal, it's just the predecessor in title "clouded" the title for some reason and the QC deed is where he/she deeds any of their interest whatever that may be and that "cleans" it up.
I was in the title insurance business for 30 years, which is why I am answering this, however if you have questions, you should contact the person fixing the problem. All the best!
