Is regular Input bugged in 2019.2?

I was following some course and ended up with this very simple code in a 2D project and the if here is not always called when Fire1 is pushed!

if (Input.GetButtonDown("Fire1"))
{
_rigidbody2D.AddForce(Vector2.up * _jumpForce);
}

After messing up around and still getting this erratic behaviour, I decided to recreate an empty 2D project with just an empty gameobject and a simple script where I log when the player pushes the "Jump" button in the update method.

And I get errors in the console about "Jump" not existing as an input...

What gives?

 

Oh gosh, never mind that. It was atually a bug in the program due to layers. ^^'
