2. Reopen the dialog and verify your changes made in 1.
The episode dublincore catalog should contain one entry for each value (e.g. <contributor>lastname, firstname</contributor><contributor>other name</contributor>…)
this is true
The contributor/presenter field should contain the data, entered in 1.
The entered value is splitted by a comma
