'input type' not exporting/importing correctly with CCK content_copy

Hello,

I think this may be a problem with the date module, but I'm not completely sure. I am trying to export content types containing date_select fields using CCK's content_copy module. I have set the input type of the fields to 'select list', however, when I export and then import the input type is setting to text field types.

I have figured out that what is happening is related to the text_parts field in the export. It seems strange though. My fields export like this:

...
    'text_parts' =>
    array (
      'year' => 0,
      'mon' => 0,
      'mday' => 0,
    ),
...

which seems like it should be correct, however this does not import correctly. If I manually change it to this, it works as desired:

...
 'text_parts' =>
    array (
      'year' => 1,
      'mon' => 1,
      'mday' => 1,
    ),
...

It gets stranger though. This data is stored in the node_field_instance table, field widget_settings. The value for 'select list' input type appears to be 0 on the cck form, however when it saves, the widget_settings field looks like this:

..."text_parts";a:0:{}...

Meaning it is saving an empty array for text_parts, this functions like it should (select_list input_type)

However, when I try to do an import with the text parts set to 0 it saves like this, which looks correct, but does not work (input_type as text fields)

..."text_parts";a:3:{s:4:"year";i:0;s:3:"mon";i:0;s:4:"mday";i:0;}...

Does that make sense? I can try to provide more information if this is not clear. I am thinking it must have something to do with the input_types defaulting to 0 (select_type) if the values for the text_part arrays are unset, but not if they are set to 0... that's my best guess and why I think this is related to the date module, and not the content_copy module, although I have made an issue there as well :).
