For issue 3 of The Cursed Library, 76281682511500331 is cover C (which is indicated in the barcode box), but you have it listed as cover D in Core. Perhaps you have C and D swapped?
Has been fixed. Thanks for reporting.
This error still appears in Core, when adding issues.
Can you check again now?
When I look in Core, it’s still the same. The issue for 3D is actually 3C
I see something went wrong with the process here. I’ve given it another try.
