Welcome to the COmmunity - First thing to under stand is how FT works - When the primay VM of an FT pair os powered a shadow VM will be started on another host in the FT cluster - in your example you only have two hosts so the shadow VM will always be running on the second host - so this explains the behavior you are seeing - you need to start the primary host for the FT pair to function properly.-
SO the question is what are you trying to accomplish? If you are looking for a DR solution FT or HA will suffice - as they are both designed for typically a single failue -
