Vanishing items from the Crafter.

What`s happening?

When I put items to output slot in Crafter it shouldn`t let me do it, but it take this item and this item disappears. I tried click button, but it doesn`t work.

Steps to Reproduce:

1. Click the output slot by some item/items (in Crafter).
2. This item/items disappears.
3. The film which is showing it is below (maybe) in Attachment.
