Turning Virtual Devices on/off does not work.

I am trying to get a Insteon Keypad's buttons to work. In short, I created virtual on/off devices and used triggers in Indigo to set the state. However, when mapping the virtual on/off device to a HomeBridge switch, it only works one way via the Home app on iOS. It does update correctly when using the physical switch/keypad.

Expected Behavior

Clicking the virtual device presented as a switch, tapping it should turn it on, and tapping it again should turn it off.

Current Behavior

The state never changes in Indigo of the virtual device. The logs show either the ON request coming in or the OFF request coming in, but not each. Stated another way, if I create one virtual device it will only see ON requests from the Home App. If I create another one it may only see OFF requests. Seems random.

Steps to Reproduce (for bugs)

Create a virtual on/off device.
Map it via HomeKit Bridge in Indigo as a switch.
Tap its button in the Home App, the state should not change in Indigo.
