I created a custom module named "Client" and it has a field name "name". I also set the default value for this field to "New Client" both in the model and in the views. However is defaulting to "New Invoice". 

I may have another field name "Invoice Ids", but it should not interfere with the default value of my field "name" right?

I may have overlook something in here. To someone that can help me, thanks in advance : )
