The 'X-Men: 3-Film Collection' Box Set seems to have been entered as the first film under the box barcode (5039036090117) and then the other two films as alternate barcodes.

I'm pretty sure this is not how we do things but as all the Disc IDs are missing and I don't have access to 4K discs I can't fix it.

Surely, if you don't have the Disc IDs, you can't put in the Box Set contents until someone does.

What needs to happen?

Out of curiosity, I downloaded the profiles and examined the setup.

The box set is configured as a Digipak (with Slip Cover) and it contains three (3) 4K/Blu-ray combo sets. I assume this means there are six discs and they are not individually packaged.

The Parent profile has no cast, crew, audio, Disc-IDs information and box set content is currently empty.

An attempt was made to add box set contents ("adding box set content for profiles separately provided as clone from mother.") on October 18, 2018 5:02 AM, but it must have been withdrawn (it was not approved).

It appears three (3) alternate UPC profiles were subsequently posted (none of them contain any Disc-ID Info) on October 18, 2018 5:02-5:05 AM, and were approved that day.

So the Parent doesn't currently contain any box set content, and as far as I understand, it should be populated with child Disc-ID profiles.

The question is will there be six child profiles (like a box set) or three child (4K) with corresponding sub-child (Blu-ray) - like a combo set.

I suppose it depends on how the discs are packaged, if the 4K/Blu-ray are housed in separate non-UPC keep cases inside the box set then that would make them definite combo sets.

Just my thoughts.
