The different bags from 20th anniversary but offering the same loots count the same items several times

Describe the bug
See the below screenshot, it seems the items we can loot in the different bags are listed for each bag, but then they're summed up.
As you can see, with account-wide mode each bag shows on the screenshot 3 missing mogs and 54 total. The upper section then shows a total of 216 (544) and 12 missing (312). This should be factored and deduplicated as it lead user to think more things are missing than what's really missing.

To Reproduce
Check missing transmogs from these bags

Expected behavior
As each bag count the same item, it shouldn't sump up the same items in the upper section count.

Yea, luckily it's only duplicated like that in the minilist as an exhaustive way to show that each bag contains the same content. But I suppose it can lead to more confusion.
We actually have a lot of existing places that skip this extra 'filling' process in lists and it seems like this would be a good fit for that as well.

while the tooltip will continue to show missing items, without them directly being added to the minilist
