Crossref plugin not receiving title metadata in most recent 3.2.1 testing.

[AhemNason]

Running a test on client data with Crossref test credentials and I'm running into a failure with this error on submission with the Crossref plugin...

<?xml version="1.0" encoding="UTF-8"?>
<doi_batch_diagnostic status="completed" sp="a-cs1">
   <submission_id>1430036899</submission_id>
   <batch_id>_1592519078</batch_id>
   <record_diagnostic status="Failure" msg_id="56">
      <doi>none</doi>
      <msg>Deposit contains title error(s): Title name value is missing from the title element</msg>
   </record_diagnostic>
   <batch_data>
      <record_count>1</record_count>

      <warning_count>0</warning_count>
      <failure_count>1</failure_count>
   </batch_data>
</doi_batch_diagnostic>

If I check the XML export, title field looks like this:

        <titles>
          <title/>
        </titles>

The article has a title and I've never seen this happen before, so I suspect it's a hiccup with the latest 3.2.1 build we're testing.

@AhemNason, what is the language setup on that journal? Are you navigating the install in a language other than the journal's primary language?

[AhemNason]

primary only (in this case, English)... bilingual metadata is enabled but this was all default and using existing metadata... and because it's live data, I also know that it successfully registered prior. The DOIs were marked "active" before I tried a test deposit using our test creds.

[asmecher]

And the journal was previously (seemingly) working fine with OJS 3.2.0-3? (Or were they on an older version?)

[AhemNason]

They were previously on 3.1.2-4. Not sure when the update was applied for this test instance by @jmacgreg

Thanks, @AhemNason! @defstat, could you take a look at this? It's possible that it affects 3.2.0 as well, since this upgrade went from 3.1.2-4 to pre-3.2.1.

(@defstat, a reminder about this)
