I think this is an error and not a missing comic…
Either there is another variation of this comic or the Core has an incorrect cover. The comic I have in hand has the issue number in the upper right corner.
The barcode is 75960620455700516.
I believe that barcode and the below images should be used to update 4C.
@Reinharc this became extra confusing because I searched at the barcode you mentioned, which lead me to issue #5C 
When I zoomed in on the barcode located on the backcover I noticed though.
I guess the image listed at #4C was preview art. I corrected the entry with your covers ánd added the barcode. Thanks for reporting!
