Cannot disable snat in iApps

Hi,

I have recently stuck with an issue on LTM which seems odd. When I set Source Address Translation to None in normal VIPs, client addresses get to the servers just fine but when I do the same thing for VIPs which I have created using iApp templates with the same configuration, client addresses keep getting translated to the inside interface IP of the LTM. It seems really strange to me because the procedure I take to disable the snat for both of them is the same but I get different result. I will paste the configuration of both here and I will appreciate if someone can help me about this.
