How come some titles in my wishlist aren't showing up?

There might not be a giveaway for it...?

This seems to happen to me a lot with "special" or "complete" editions of games on my wishlist. They get counted separately.

I think only the top 10 (or 20?) of your wishlist will be highlighted on steamgifts.
(is this even a steamgift feature or is it an enhanced steamgifts addon feature? can't recall^^)

This is kinda problematic as the steam wishlist is highly buggy and will either not let you change the order of your entries, not save it or randomly re-order it sometimes.

In any way there has to be some limits as you can imagine that it would cost a lot of resources for sg to do this for all the people with their hundreds of wishlist entries.

Packs are different products, and Injustice is mostly sold/bought as the complete package now.

btw it happens to me too...i've 100 in steam wishlist and no one in steamgift wishlist.

There is for example 1 mad max giveaway, i see it if i search in "all" and not see in wish...it's 3 days ca that happened

I've actually been having same issue.
I have 122 wishlist items and some seem to simply not show up.
Its really odd too because the one in particular was neither last alphabetically nor occupies end/beginning of wishlist for me. The URL is exactly same as well as title as on the wishlist, no its not an 'edition' or pack.
If it click through to Steam from the GA, it sends me to the page that says that this item is on my wishlist.
Steam account is synced yet it doesn't show up in the filter.

I'll almost guarantee it's a different package, like a Complete, Limited, etc that you can't add to your wishlist, but is the one people always buy. That happens with several games I want.
Likewise, there's games I OWN that do show up for the same reason cause it gets marked as game, and DLC, rather than both together as a complete edition.

Kinda wish SG had it's own wishlist feature to be able to add in those weird games that don't show up.. but alas..

Talos Principle. 6 days remaining. On my wishlist. Doesn't show up. Not a pack not an edition.
