How to show glyph-names?

When I open a .ufo-file, all glyph-names are missing in the font-window. How do I get these back again?

Thank you!

Scale. There is a slider for that in the bottom right corner.

Normally, the names are only hidden when you zoom out. Can you send me the .ufo?

Thanks! It works.
