Cannot create sub-task from task

When trying to create a sub-task from an existing task, the following error occurs in my installation. The field "Afregning" is a custom field.

The problem only occurs when creating a new sub-task with the button below an existing task. When creating a sub-task from the left pane there is no problems.

Cause:
Can't find resource for bundle java.util.PropertyResourceBundle, key Afregning

java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key Afregning

Stack Trace: [hide]
