When inserting a 'Label: Value' style row into an article or clause, there is no need to add a colon. This is added automatically.
If you add a new row (paragraph) to an article or clause and include a colon at the end of its name to match the formatting of the other rows, you might notice that when returning to this section or exporting your specification, the colon appears duplicated (see below).
This happens because, when saving, the system automatically adds a colon to match the formatting of other specification rows. To fix this, just delete the colon from the heading, and the system will fill it in for you.
Note: When editing the row heading, you'll see that the second colon disappears. Simply delete the remaining colon and save.
