Blank space in an exported plan is often due to some extra "returns", or line breaks, at the end of the last block of text in a section. This generates extra blank lines in that section, which will result in added blank space. The video below walks through removing this extra blank space from your plan exports.
To remove the blank space:
1. In your downloaded plan, locate the topic above the blank space.
2. Navigate to that topic in the Plan tab in LivePlan. Click the Edit button to edit that section
3. At the end of the text, remove any additional lines, then click "I'm Done" to save the changes.
