No, I am sorry, there is no way to fix this. Since UddeIM does not create HTML messages (using phpMail) nor Joomla (using mosMail) the only way would be to strip the BB codes.
You are right, the combination "BBcode allowed" and "include message text in notification message" looks quite bad. Maybe I will fix it in a way that either the first or the second option can be enabled.
