Start/Stop trait on multiple nodes not working

When starting or stopping a device(node) with Start/Stop trait enabled and debugging to show the full object, I see a params.start object with the correct value for that command. When starting or stopping several devices(nodes) with the same command, only the first node processed has the params.start object.

Node Red V3.0.2
node-red-contrib-google-smarthome V0.4.3

EDIT: To resolve this issue, I created a global variable and assigned the value of params.start to it when it exists and re-use it on consecutive nodes with Start/Stop command type.
