WEBENCH® Tools/TPS61072: Simulation of enable / disable does not disconnect the load

Part Number: TPS61072
Other Parts Discussed in Thread: TINA-TI, TPS61032, TPS61256

Tool/software: WEBENCH® Design Tools

I have been attempting to simulate the documented behavior of the enable pin on the TPS61072 using Webench without success.  Webench does not appear to simulate load disconnection, with VBAT voltage on VOUT after setting EN low.  When implemented, the EN pin will be activated by a microprocessor output pin.

The Esim report is attached - is the problem with Webench, with my understanding of the TPS61072, or with my circuit?  Or perhaps a combination of these?

Thanks!
