How to remove an extra character E.001

I’m an instructor using Glyphs Mini 2 for the first time and I’m having issues with an extra character that I somehow created while copying and pasting in my Adobe Illustrator data. With the extra character I’m no longer able to export the font. Does anyone have suggestions or tips on how to remove the extra unwanted/needed character?

Thanks in advance for the help!

Delete both glyphs with this name.

You can use the search field in the bottom right to search for them. Select them and delete them with the minus button in the lower left.

Thank you @FlorianPircher ! As a new user, I completely overlooked the “+/-” buttons within the Font Window.
