What's happening:
Document Questions that have "Number Question" selected under the "Displayed text" section of their setup window are not appearing as numbered when viewing a completed Document or Document Preview.
Possible solution:
If the Questions are in a Section or Group, numbering will need to be enabled in the Section or Group and a preferred format selected for "Sub Element Format".
Select the Section or Group to bring up its Edit window.
If the Questions are not under a Group or Section, then numbering will need to enabled for the Document body.
Select "Main Body" to bring up its Edit window.
