As John said , with multiple remotes, manage your engines is the key. It can get even more confusing if you create lash-ups helter skelter ignoring one remote. The more engines, the worse it can get. The more engines, remotes, lash-ups…more chaos.
Its really not so bad once you realize you could be creating the confusion. I love creating lash-ups & just created so many conflicts adding & deleting from one remote to the next I decided to start with a clean slate. Your problem may not be so extreme & could be solved by just changing the engine address as John suggested.
