Workaround:
This issue can be avoided by configuring the settings via XML. The issue is limited to input through the GUI, as shown in the figure above.
 
    <ztna>
        <rules>
            <rule uid="">
                <destination>test_1.local</destination>
            </rule>
        </rules>
    </ztna>
 
The behavior is fixed on v7.2.9 and v7.4.3.
