TinyMCE Not Saving Some Information...

[eluser]drshields[/eluser]
I'm not sure if this is a CI problem or not. I'm currently using TinyMCE in a textarea and many changes I make are posting correctly such as font-bold, font-italic, font-underline, etc. The post and save the in the database just fine as they are supposed to.

However some elements are not working correctly, such as the font color, font size or font family. Has anyone else had problems getting some TinyMCE elements to http post incorrectly in CI? Any suggestions?
