Indesign Outline ALL fonts

Many thanks in advance for any help or advice given.

Why does some font text move when outlined with this script ie. text moves down from original position?

tell application "Adobe InDesign 2025"
	if not (exists document 1) then
		display dialog "No document open." buttons {"OK"}
		return
	end if
	
	display dialog "All fonts will be outlined"
	
	tell document 1
		repeat with aStory in stories
			try
				create outlines (text 1 of aStory)
			end try
		end repeat
	end tell
	
	display dialog "All text has been converted to outlines." buttons {"OK"}
end tell
