Existing glyphs not showing up

Hope you are doing great!
Help needed:)

I’m using Glyphs 3. When I type some letters, they won’t show up. However, they exist.
Screenshot of existing letters:

Screenshot of not showing up:

When I try to create glyph with “a”, it says that the glyph already exists. The font was done for 99%.

Tried to reinstall, however my link was expired.
Does reinstalling solve the problem?

Thanks,
Gulya

Try the latest beta please. Go to Glyphs > Preferences > Updates, activate both checkboxes and press the Update button.

That sounds like the download link for your .glpyhs3license file. Make sure you make a backup in a safe place.

If you want to redownload the app, get it from the ‘Get Glyphs’ page. (Link at the top of the page.)
