Hi,
I just published my first book on OMP. In the printed editions, it shows the publishing date and then the words “Hijiri calendar”
Steps I took leading up to the issue
Published a book with softcover, hardcover, ePub, HTML and PDF formats. Printed formats have a future publication date. I don’t recall any setting about calendars.
What application are you using?
OMP 3.3.013
Additional information
It would be nice to avoid having titles of empty information (both Hijiri and physical dimensions). I couldn’t find a setting for disabling it. I am using the default theme.
