Courtyard layers disappeared.

Description

When opening the following project and then PCB editor there are no Courtyard layers in the Appearance window while these layers can't be hidden in Board Setup. When I open another project I have them as usual.

May be it is not bug, but I just don't know something.

This project was not created in usual way. Here is the description how I got it:
