Is anyone familiar with the Contacts Plus app? I have a problem.

[anon(8734726)]

I used this app on my old phone and it worked great. I had two Gmail accounts on that old phone and this app would show contacts from both of them and list both accounts. I am no longer using one of the Gmail accounts but when I installed Contacts Plus on my new phone, it is still showing that old account which I do not have installed on this new phone. Any ideas?
