Not creating forum nodes correctly

I got mailhandler to create nodes with taxonomy terms. However, the problem is that it's not create forum topics correctly. Below you will see the export of my Feed Importer. To test, I sent an email and did the import. The forum node got created with the correct Taxonomy but it doesn't show up on the forum because it didn't create an entry in the drupal's forum table. If I edit the node and save it then it add an entry to the table and the forum topic shows up. I tried with the latest release version and the dev version and neither worked. Any suggestions? Thank you
