"Underline" custom styling not appearing on ad-hoc clauses

Hi all,
small bug I found when creating a ad-hoc clause with style “Underline” enabled. Whilst it is shown in the preview, the underline neither appears in the PDF Preview or downloaded Word file.


Switching the clause from ad-hoc to library clause does not seem to fix the issue.

Found a fix: not using the “Custom styling” option, or the special codes - neither of these work with underline.

However, adding \text\ does work.
