Here is an example from my own pages.
First, here is a screenshot of my "Collections" page:
Please note 2 things in particular here:
#1 - My collection called "For Sale or Trade" is exactly that, only cards available FS/FT and listed as such, but "counted" in the total (429)
#2 - Please note the number for the "Philadelphia Phillies" collection (10,350), as I will be drilling down on that page next
Now, for the Phillies collection:
In "collection" - 9358
In "want list" - 983
In "in transit" - 9
Total - 10,350
Basically, the info on the Collection/Collections page is giving a sum of all the portions (Collection, Want List, FS/FT list, in transit, in transaction), not simply the cards in "collection".
Remember also, that if you go to a card's page, it might say "28 mentions in collections" and then when you click that link, 16 are in "collection", 8 are on "want lists", and the other 4 are "FS/FT". So it's consistent across the site, and Admin has done this by design (like I said, it's always been that way). Maybe what I could suggest in the tracker is the expansion of that table. Instead of it having the single column of "Items", we could have it broken into "Collections", "Want list", "FS/FT", "Transit", "Transaction", and then "Total Items". My biggest concern with requesting this is it's feasibility because this may not be very mobile-friendly.
In the meatime, before anything is changed (if it's even changed), the term "Collection" is used in two ways. First, anything logged here whether it be FS/FT or want list, is considered an "Item" in your overall collection, while your "keepers" are listed as being in your "Collection" within your overall "Collection".
