Cards gets missing in HUT

So as I finished several objectives in HUT (Early Access in XP Season and Fresh Ice in Events) and claimed these rewards, I noticed that these did not go to my collection.

The reason why I am absolutely sure of this is that while completing all objectives for Fresh Ice you were supposed to get Luke Evangelista (rating 81). I got him and lots of other collectibles as well as other rewards in my Item Inbox and sent all to my collection. However, none of these rewards ended up in my collection. I am also unsure when it comes to the packs that I opened but I could swear that I had cards with higher ratings.

What would be next step to get these cards back? 

I highly appreciate any help I can get!
