Hi Daniel,
We had a long discussion about whether, for a new workbook, it’s better to include children of elements, or make it a user-selectable option.
In the end, we decided to make it the default. You can go back to NOT including children of elements in the settings for a Worksheet.
What decided it in the end was that during testing, I kept being surprised when the list of elements was smaller than I expected, then remembered I had to click the ‘children’ option, and this happened so many times we decided that exporting children should be the default.
