Can't grab last 2 keys in the Reception Room

And I can't find an update for this game. No downloads or updates available.
Please help...

I've opened the book, see the 2nd key but I can't highlight both keys to complete the final set of 8.

Yes, that's exactly why I'm here.
I can't get the last two keys to match and I wondered if anyone else had the same problem.

It seems there is....

I've just restarted the game and when I got to the key puzzle, I picked up the fish keys first, which was the one I couldn't pick up before.
Once I'd done that, I could pick up all of the keys. I hope that helps you.
