IndexOutOfBoundsException when viewing Overview Planning Board

IndexOutOfBoundsException is thrown when viewing the Overview Planning Board under the following use case:

• Assuming you have a Story Points custom field
• Modify the Story Points field to apply to every issue type except SubTask (since we never want points on subtasks)
• In GH Planning Board config, set the Story Points to be shown in the List view of the Version Board (Default issue type of Bug is shown)
• Click "Apply to all lines"
• Go to the Planning Board Overview where you have at least one SubTask and you get this error:

• Go back to the GH Planning Board config
• Select SubTask in the issue type drop down.
• Notice that "None" is now set as the extra field for the list view on the Overview Board. It was previously "Versions" before the change above.

It appears that when a field does not apply to an issue type it creates a shorter array and therefore this exception.
