After the removal of The Witcher Adventure Game Beta from our libraries, a blank space appeared on the shelf where it used to be. Account refresh doesn't help, and no matter how many times I rearrange my virtual boxes, the blank space keeps coming back. It's been a while since the Beta was removed, and this problem still persists, when can we expect a fix?

This bug exists even longer than the time of TWAG removal. That only made it more widespread. And sadly there is no official response when this will be fixed.
