Font not working in Motion (v5.4)

As you can see in the screenshot below, I've tried a .tts font and get the exact same results, now I am using a .dFont that is perfectly recognized in any other Mac application just like the .tts, even in the font preview of Motion as seen in the screenshot is perfectly fine, but in the canvas it appears as an Open and Closed Lock Glyph... Why does this happen? How can I fix it?!...

The Font just have the "A" and "B" keys changed, but this is not a problem because it uses default glyphs in the other mappings.

Btw, It works just fine in any other app such as TextEdit, Pages, Numbers, Etc...

Even Copy and Pasting fonts between apps can handle the format, but when pasting those characters in the canvas It just won't work, it pastes the Lock Glyphs...
