[Unit Description -> Rooms Availability Calendar] Labels can't be hidden

There are two labels I am trying to remove:

Label 1:

Admin -> Structure -> Content Types -> Unit Description -> Manage Display -> Field Type [Rooms availability calendar] .... can't make the label go away. Above/inline/hidden don't seem to do anything.

This is my setup: https://www.drupal.org/node/1782238

Label 2: There is another label for the calendar which I can't remove, this second label is output by the template rooms_availability_field_calendar.tpl.php:

<div class="<?php print $variables['classes']; ?>">
<?php foreach ($rooms_availability_field_calendar['calendar'] as $unit_calendar): ?>
  <?php print render($unit_calendar); ?>
  <div class="cal">
  </div>
<?php endforeach; ?>
</div>

the 3rd line. BUG: Removing this line causes the calendar to stop loading data via ajax.
