But mayhaps the game isn't properly locking the mouse to the game monitor, and your clicks are unintentionally affecting the trainer UI. I have this exact problem with the Dying Light trainer on monitor 2.
I don't know if Imgur links are allowed but sadly that can't be the case.
Since I haven't started the game yet. Normally I start the trainer, move it to the other monitor and then start the game.
But once I move it to the other monitor is when it happens. 🙁
