My .otf and .ttf exporting differntly than my.woff

I have an issue when exporting my fonts. The otf and ttf have substitutions whereas the woff doesn’t. The lowercase “x” is showing up as a multiplication symbol. It doesn’t do it for all my weights/italicized either only 3.

Thoughts?

For some reason the lowercase “x” shows up as a multiplication mark in FontBook. The fonts work in InDesign but not in Keynote. In Powerpoint it shows up as a hollow “x” which leads me to believe there is an issue with the paths?

The hollow letter problem used to be caused by having a path duplicated on top of the other.
