It's because you have more than one tnsnames files in your directory. We're reading ALL of them.
Thanks again Jeff.
Yes, I had several tnsnames.ora files because we have one golden on a server and whenever it gets updated, and we reboot our own laptops the local tnsnames.ora is updated from the golden and before that a script renames the local file to something different (with time and date stamp). I moved the other files out of the Admin folder and I see only one entry.
Thanks a lot.
