TPS57140-Q1: Discrepancy in Phase Margin between System Information page and Bode Plot in Simulation

Part Number: TPS57140-Q1

While doing analysis of one of the regulator circuit, I came across a scenario where different pages of the WebBench of the same circuit showed significantly different results. In the Bode Plot page, it shows that the phase margin is 34 degree. Whereas in the Customize page, it showed 57 degree.  Please see attached PDF for circuit and the output.
