Duplicate text after publish with static HTML

Hello,

When I publish my Adobe Edge Animate creation with the "Publish Content with Static HTML" option ticked, I get black duplicate text added to my navigation symbols. See below - the top "home" is without the static HTML option, and the bottom one is with. Note the small black "home" under the bottom yellow "home". Does anyone know how I can prevent this?

Software version is 3.0.0.322.27519

Thanks :-)
