Letter won't export when trying to export the entire font

[ShammaAlMheiri (Shamma)]

Hello,

I’ve been facing an issue on glyphs that when I try to export my Arabic font, one letter does not export along with the rest. It also moved down all the way to the bottom of the letters section and is no longer in it’s original place. Is there anyway to resolve this issue? I have attached an image of how it looks

Thank you

You have set the glyph to not export. (See the red sign in the top right.
Right click it and click the “Export” menu item. Or select it and check the box in the lower right info box.
