Imagecache Preset for More Than One Content Type

Hello,
I'm working on a site right now. Let say I have two content type (product and news). On each content type I add a new CKK image field and set the Image path column to "image/products", and I wanted to use Imagecache module to generate thumbnail for all uploaded images from those content type.

First, I create 2 new preset on ImageCache configuration page as described in http://drupal.org/node/101748, I created to preset with the name product_mainimage and product_thumbimage, set the action for those two preset and then I tried to upload several images from product content type. And so far it works and Imagecache able to generate thumbnail for it.

What didn't work was, when I create another two preset named news_mainimage and news thumbimage and try to upload image from news content type, when I upload the images, Drupal did upload it but ImageCache didn't create thumbnails for it, and when I look on the files/imagecache directory there was only product_thumbimage directory, I can't see news_thumbimage directory anywhere.

The main question is, dose ImageCache support more than one content type? Or did I've done something wrong?
Hopefully someone can help me on this, I desperate..

Thank you.
