Unable to import new kerning file since original kerning has been deleted


I wanted to start over again my kerning, so I deleted all my entries in the kerning window by selecting each line and then I pressed on the minus button.

Since then it’s impossble for me to import new kerning file. The kerning window stay empty even if I try to add kerning manually to each letter.

Is it a bug or have I deleted something important when I cleaned all my original kerning?

Thank you!

Which version of the app and the OS are you running?

Does reopening the document help?
