we’ve noticed that there is a key missing in the en_US locale for OMP.
The key catalog.noTitlesSection, which should be in lib/pkp/locale/en_US/submission.xml does not seem to exist, which leads to the value ##catalog.noTitlesSection## showing in the frontend of our OMP. The key and translations for it appear to exist in all the other language locales. Since the translator plugin does not properly allow editing the English locale, we can only fix this manually in the xml files. Please add this key in the future!
