Please find attached a little export of a confluence space called "Placeholder Demo" which demonstrates this issue. After imported into XWiki you'll find a Page ./bin/view/PD/Placeholder%20Demo%20Page/ which shows the following:
"First name: Please enter your first name here
Last name: Iverson
Note: Only the last name “Iverson” has been entered, but not the first name."
The text "Please enter your first name here" is just the placeholder and should not be converted to normal text.
