Where is "Edit labels" ?

I am new here but have used Audacity with pleasure for a while.
Now I need to add text mark to get a survey over good and bad places in a long audio recording.
I have seen a Youtube-video and read an answer in a forum.
Both places they mention a Project tab. that I cannot find.
And “Edit labels” under “Tracks” . But my Menu is missing this option.
See attachment.
Why ?

In Audacity 2.2.2, the label editor is in:
“Edit menu > Labels > Edit Labels…”
(see also: http://manual.audacityteam.org/man/edit_menu.html)

Thank you very much !
