I have not upgraded to the 2.0 version yet. However I don’t think the problem relates to hardware faults. Definitively not when you got two of them. My problem with my Fibaro button is that it sends the different presses correctly (it can be seen in the developer Z-Wave log), but Homey doesn’t do anything with it. I have an open case with support where they acnowledge it as a problem in Homey.
They haven´t followed up the case since 6. december though, so customer services at Athom would definively not be rated as the quickest in the business regardless of a company doing a major upgrade or not. More manpower is just needed.
I would check the Z-Wave log to verify what commands Homey receives when you press the button x times. That is easy to trace. This is an example from my logs where I clicked once on the Fibaro button named internally as “Node[38]”. Look for the “Key Pressed x time” text for your spesific node:
