Edit: Animals not shown in Trading Center anymore

[Fortunanovesia]

I had around 25 animals in my trading center. Saved for some later exhibits or zoos. Now i lost them all.

Loading the trading center takes some time and when its open my storage is empty. i just bought another new animal. This one is shown and ive got 1/30 in my storage...

Ive found them. They are still in the trading center, but the game isnt showing them anymore...

Your screenshot shows you have a filter applied in the trading center.
