It sounds like its a "digital pressing error" at the "plant", I wouldn't spend any more money on more "copies".
I would contact Matador, however on Discogs it has the following on this release under notes:
"...There is a mistake with track numbers on Disc 2. Number 6 is missing so we jump from 5 to 7." Whatever that means...
Unfortunately I do not own a copy of this to validate or refute this error.
My friend/contact at the Matador warehouse in NYC is no longer (he moved onto another label distributor) so I can't ask him.
Errors like this though rare, do happen... Like when I got an early vinyl pressing of Thurston's Best Day and the pressing quality was atrocious and ended up getting a better copy later because of one pressing plant's issues...
