BB (RIM) :: Duplicate Contact List (Gmail Online Sync)

I am using the online sync function that works with gmail account. I really like this feature because my 9700 will always have an updated list of contacts.But since I did a device switch, I had to register the email account on my phone again. Now I see 2 contact lists associated with my email account. For example, my gmail has 200 contacts, so on my BB i see 400 contacts all duplicated. If go into Contacts Options -> Contact Lists, I see the same gmail account twice. There is no option to delete one.

(This is only for contacts, as far as email setup, I only see my 1 email account setup)I dont mind just deleting all the contacts on my BB and then resync again, but I can't seem to find a way to delete all the contacts on my phone.
