When adding the TPB by scanning the barcode, or entering the barcode manually, the suggested item to add is swapped to the different barcode for individual magazine issue #2. As if the two barcodes are incorrectly aliased together.
Note, show missing doesn’t show a TPB #2, and in fact TPB #1 doesn’t have a #1 designation, which may be a factor in this mixup between individual issues and collections.
TPB #2 barcode: 978178774433252499
Magazine #2: 79361173690000211
