Removing Highlight from Marker Tool Text box?

Hi Nathan, 

I tried replicating the behavior that you experienced, but markers displayed without any issues when I added them to a new project file. 

Try the following to help address the behavior: 

• Import your slides over to a new project file
• Repair your Storyline 360 installation

If the issue persists, would you be willing to upload a copy of your project file here or in private by opening a support case so we can take a closer look at the formatting settings of your markers?
