The caption/label rendered on node/content page is not translated.
The simplest way this could be fixed is by using t() on line 160, of field_group_table.module.

Change below line of code:
$label = check_plain($group->label);
to
$label = t(check_plain($group->label));

So this is incorrect usage of t(). Field labels shouldn't be translated in this way. IIRC, this should be done with i18n. In this case the i18n_field module.
