Phone confusing Contacts?


The only real problem I have had with my DX is the phone confusing contacts. 


One example is I added a new contact named "Bobby" and it added it to an exsisting contact "Rob". 


Another and more annoying one is with the New Message Widget.  I have a contact named "Jen" and "Jenny" in my phone.  Completly different contacts in the list.  When I get a text from "Jen" the widget displays its from "Jenny" and will quick repond to the "Jenny" contact.  But if I got into messaging, you can watch the phone change the sender to "Jen".   This happens with all contacts that are similar. 


Anyone else have this problem?


Other than that, Im loving this phone.
