How can Missouri 610.140.7 say a record will be “closed”, and 610.140.8 say all your rights will be restored?

How can Missouri 610.140.7 say an expunged record will be “closed”, and 610.140.8 say all your rights will be restored?
I had a class c felony from 1990 removed but it’s still on my record. Section 8 of this law says all rights lost as a result of this conviction will be restored. With this record still there as a “closed” file, I still can’t pass a background check for a firearm.

Criminal Defense Attorney Justin’s Answer
This is going to be difficult to answer in a post. My guess is you will need to speak to a federal attorney because federal law may still prevent you from owning a firearm even if state law has cleared you. You might also have other convictions that are holding you up: any conviction for drugs or domestic violence can prevent you from getting a firearm.
