First this: Section Access doesn't depend on the QMC or the Publisher. It's embedded in your document and is considered as document security (or file security). This means that even when no server or QV desktop is near, nobody will be able to access the contents of this file without proper credentials and permissions.
If you publish your document to the correct user (yourself) in the Distribution tab, then DMS/NTFS rights should be ok. We cannot deduce that from your screenshots, so you should check it yourself.
Is Seciton Access enabled in this document? If so, is your account present in the SA table?
Is the QDS able to reload the document?
