{$submissionTitle} email tag sometimes not pulling submission title in co-authors notification email

[alexxxmendonca]

Describe the bug
Sometimes, when the submitting author sends an email requesting ORCID authorization to one of their co-authors, the email tag {$submissionTitle} is not populated with the submission title.

The author receives an email like this:

Dear {$authorName},

You have been listed as an author on a preprint submission entitled "" to {$contextName}.

To confirm your authorship, please add your ORCID iD to this submission by visiting the link provided below. This can help for a faster approval and posting of the preprint.

{$authorOrcidUrl}

Here's an example of an actual email that was sent from SciELO Preprints to an actual co-author:

This doesn't always happen, though. Sometimes the email goes with the submission title just fine, but most of the times this doesn't happen. I am not sure if this has anything to do with the languages form and whether the tag is pulling data from a specific language, or the stage of the workflow the submission is at...?

To Reproduce (not sure this will be useful given that it doesn't happen 100% of times)
Steps to reproduce the behavior:

1. Make a submission in OPS with ORCID plugin enabled.
2. Add a co-author with an email to which you have access to
3. Check option to send ORCID request
4. Check email to see if submission title is appearing

Expected behavior
Show submission title according to email template language or show the one language that is available (in case only one language is filled).

Additional information
I'm using OPS 3.3.0-13 and ORCID plugin 1.1.3.6.
