i wanted to remove the add line from this tree view but it's not working 

this is my code :

<xpath expr="//group" position="after">
    <h5> <strong>Products</strong> </h5>
    <field name="picking_ids">
        <tree create="false" delete="false" editable="false" multi_edit="0">
            <field name="company_id" invisible="1"/>
            <field name="name"/>
            <field name="scheduled_date"/>
            <field name="state"/>
            <field name="location_id"/>
            <field name="currency_id" invisible="1"/>
            <field name="amount_total" sum="Total delivered" widget="monetary" optional="show"/>
        </tree>
    </field>
    <h5><strong>Fees</strong> </h5>
    <field name="type_service_ids" >
        <tree create="false" delete="true">
            <field name="name" />
             <field name="price_subtotal" string="Fees amount"/>


        </tree>
    </field>

knowing that i inherites the create invoice view to show the picking that is been invoiced yet i still can add a line although im using the create=false editable=false attributes
