Hi,
when adding a file, the predefined title is not adapted to the generated field html, if the site language is not English.
The cause is in the html( $default ) function of echt field type. The $field->default is passed with the localization function ecs_attr_e(), so the data-default value turns into "Titel" in German, for example. This doesn't work.
Solution is to just change all esc_attr_e() calls inside the html() function into
echo esc_attr()
in each /classes/fields/class.field.{type}.php
