Xseries :: Unable To Delete Messages In X2-01?

I performed a phone switch in my X2-01 to transfer my contacts and messages from an N2690.The data connection was lost before it can complete so I had to do a second try. I noticed that there were a lot of messages with empty headings in the X2-01 which I did not have in the N2690. I tried to delete them, but I was getting the message "Error occurred. Deletion not completed." over and over again.When I used a PC Suite, the empty messages displayed with their body and I recognized them as the previously deleted messages in the N2690. I was unable to delete the messages using the PC Suite even after restoring to factory settings (including personal data).
