Dept of Truth 1 6th print 0

[fastballspecial]

I preordered quite a few of these and I understand they had a problem with cover images. 

Can someone plainly explain to me what happened here? Half my books are one cover and 
then the rest of the Yellow corrected cover. Where does the error come into play here? I know 
they messed up the 1/25 variant. 

Ive read up on this and still dont quite understand it.

When they first delivered it the normal cover was delivered as 1:50 and the 1:50 cover was delivered as normal one. They corrected it by sending the stores the same amount of copies they've received previously.

So, basically the error copy has the wrong barcodes and they reprinted the right ones for the stores about two weeks later
