Missing player in layouts

Hi,
I seem to have lost a player from the layouts list. See attached list of players in the “Players” section of Setup and the list of Layouts. As you can see, “Temple Blocks, Cow Bells, Drums…” is missing from the Layouts.
What have I done wrong?
Thanks,
Peter

It’s not difficult to delete a layout by accident. There’s a button to make a new part layout at the bottom of the right panel, after which you can tick the relevant player. Alternatively there’s an option on the Setup menu to create default part layouts.

Thanks a lot. That did the job!
