Recreate Baskerville Italic Font With Extra elements

I have already designed each alphabetical letter and numerals with the design requirements through adobe illustrator. I also added it into the glyph app, I just need assistance with exporting it. It keeps showing "error" when exported as otf. The font can be exported but when used, most letters are missing.


Ideal skills and experience:
- Proficiency in Glyphs Mini
- Strong understanding of font design, particularly Baskerville Italic
