The problem of exporting the font in version 3

When the font is exported in version 3, the spaces between the characters change, unlike what was placed inside the application, so that the characters are overlapped on top of each other.
Is there a solution to this problem?

Can you be more specific? Or can you send me the .glyphs file?

Can you send me the .glyphs file?

I’m having a similar problem, only the characters are getting distorted, not just overlapping. See the ‘U’ in the bold weight, and most lowercase characters in the regular weight.

Is this Illustrator and you exported as TrueType?

can you at least post screenshot of the two glyphs that don’t match?

Thank you, I fixed the letter over some issue
But what is the problem with the Arabic characters does not work Kerning
