Running RoboHelp 2019 new. Generating Frameless output for Orange skin. Configured mini-TOC to use heading levels 2-3.
If I turn heading level 2 text into drop-downs, the mini-TOC displays the text twice. For example, "OverviewOverview". See the following image (captured from output viewed in latest version of Chrome for Windows):
Issue also exists in MS Edge and Firefox browsers.
I suspect you are using Heading styles for the hot-spot. Known issue covered in another thread. Will be fixed in next update.
Which reportedly is coming soon... Good to know! Thank you!
