Space = 0

I readjusted the width of my “space” glyph, but now when I export the font and use it in Illustrator, every time I hit the spacebar I get 0’s instead of spaces. How can I fix this?

How did you install the font? With Font Book or in the Adobe Fonts folder?
Have a look here:

Thanks a lot, it fixed the problem of spaces being zeros, but now, for some reason it only types in all caps in photoshop.

did you delete the font from Font Book?
