Thanks for reporting this issue. Regression introduced by https://cgit.freedesktop.org/libreoffice/core/commit/?id=e1d0846e060d2b3faedfe1a5877303037d8cf4d6 which is already reported in bug 141171. I believe the root cause is the same... *** This bug has been marked as a duplicate of bug 141171 ***

That was a tricky one to avoid as a duplicate: FILEOPEN vs Export as PDF, Impress vs Writer,... :-) I'll keep an eye on the other one and will validate any fixes with my documents. Since in the meantime I had created an ODP document which exhibits a similar issue, let me share this here and adjust the description - just in case.
I verified that now that bug#141171 is fixed, this is fixed, too.

Yes, the DUPLICATE of can also be set to VERIFIED
