Create outlines in illustrator on a bitmap font fills alpha channel

Im having an issue where I use ‘create outlines’ in illustrator with one of my fonts. A select few of the letters will fill in the Alpha channel and change its colors but the others will work just fine. All of the original images before creating the font are transparent PNGs. Any ideas what is causing this?

Hello codytcheng, welcome to the forum.

Without have access to the font in question, it’s hard to tell anything, that might help you.

I tried to upload the .OTF but received a message that I was too new of a user to upload files.

Yes, the forum rules.
Hm, you can load your .otf as .zip-archive to a file hoster services like or and place the link in here.
