Mouse X Value sometimes not 0 while mouse not moving

As i understand it (and i am a beginner), the mouse X value should be 0 at rest since its a delta. Yet, sometimes it will get stuck on a value like 0.07 and up to more than 1.0, eliminating the possibility of using a deadzone for my purposes.

Is this behavior expected or is it a bug or a mess up on my end?

I fixed it by using Get Input Mouse Delta instead, its values consistently go back to 0 at rest unlike Enhanced Input Action’s values.
