Missing track piece in Track Libraries

[Lightning01]

For some reason Kato Track Library has track piece 20-111 missing from list. I don't know
if this happened with  last update or not. Attached is screen print of Track Library. Run Windows 10

Maybe you've accidentally hidden the part.

At the top of the track library pane, please tick the 'Display all' checkbox.
Now, the part will appear with a red circle behind it.
Right-click it, and select 'Show'.
Untick 'Display all'.

It is amazing how we mess up things & don't even know we created a problem for our self by accident. Thanks David I will try to do better.
