Clock Gating Unsuccessful in WAIT mode

I’m trying to configure the device to gate several clocks when it goes into WAIT mode from a WFI instruction.  From my testing it appears that the clocks are not automatically turning off in WAIT mode, and I can’t figure out why.  I have verified that it is getting into WAIT mode, and the CPU stops executing instructions.  Do you know of anything that would prevent clocks from gating even though the device is in a WAIT state?  This is a step to reduce power.
