This shouldn't occur unless you have LP mode turned on from within the In Command....
The command to run in propane mode comes off the BCM and in this post I showed where that signal comes from...
So either you have both heating modes turned on or you have an issue from within the In Command
If you set water heater mode to propane then simply TS whether the igniter is ticking and feel both solenoids at water heater to see if they open as well.

The water heater is designed to work on Propane, Electric or Both... So, having both heating modes turned on should not cause a "fault" to display. The In-Command system may not be "talking to the water heater properly" causing the fault, but the water heater is operating "normally" if it is in any of the three "selectable modes" (LPG, Elec or Both).
I don't have any experience with troubleshooting the In-Command/water heater interface, but it doesn't seem that it should be displaying a fault if both heat sources are selected. The water heater is designed to operate that way.
This issue shouldn't force a "limitation on the water heater operation" that restricts use of normal operation of the water heater, but stranger things have happened with "new system technology"... Hmmmmm ??????
