It is entirely non-obvious from this screen that placeholders {minutes}, etc. must be used.
Furthermore, the description for Short date x days phrase doesn't make any sense at all (to me).
Suggested Fix
Show placeholders or explain parameter usage in the description
Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XF release (2.3.0 Release Candidate 1).
