Field titles not translated

I have an issue with the email field where in the drupal translate interface the field title shows up and can be translated. But on the front end when the form loads the title shows up untranslated.

I've worked around this by adding:
$element['#title'] = t($element['#title']);

to html5_tools_field_widget_form() before the switch so that it applies to any return statements.

I found some details about translating the forms here: https://api.drupal.org/comment/50238#comment-50238
