Summary:In the text box when the list starts with number 1, It gets Auto indented from left however if the same list is starting with number 2 or onwards no auto indent is being observed.
The issue occurs only if QuarkXPress has AutoCorrect XTension installed and enabled in the XTensions folder .
Solution:
To avoid this either disable the XTension from the XTensions Manager or remove the AutoCorrect XTension from the XTensions folder.
