You may find that a lengthy slide title in the Notes tab extends beyond the dividing line into the area reserved for slide notes.
This is a known issue. To work around this behavior, do either of the following:
- Shorten the slide title.
- Go to Home > Player > Colors & Effects, and set the Transcript >> Separator item to 100% transparency (shown below). This will hide the dividing line. And you may also want to add an empty line of text to the beginning of your slide notes to provide some space between the slide title and the slide notes.
