I get the Green Eco Footprint on most objects that I upgrade to Energy Efficient. I don't use Fuel Cell upgrades, so I haven't seen the Industrial Eco Footprint. Those tooltips are normal for the upgrades you've done. It's a little surprising that the game tries to show them both but I don't think it's a bug, just an unintended consequence of players doing things the developers didn't anticipate.
@Sketch793Can you list the objects you are seeing the Green Eco Footprint on? I have upgraded one of each object to the Energy Efficient Device upgrade. I am not seeing the Green Footprint tooltip on any object but the refrigerator.
Here is a video showing that I am not seeing what you are seeing in your game:
