it's the font type that seems to be the problem? I could create the same issue on my computer but only with one callout using Source Sans Pro and an otf font.
The othe fonts were ttf fonts and worked correctly.

I can't tell you if this is a Camtasia bug they are working on.
I don't know if there's a way to convert the fonts you have to ttf or if you even should?
I see you have a lot of fonts that don't work so you should probably contact support.Chat will be open for a few hours today.
