2D Colliders are colliding but not touching

I’ve been trying to switch from a custom raycast physics system to one driven by Box2D and I’m stumped by this problem:

They seemingly collide, but leave a rather huge gap between each other. The sprite is using a Box Collider. In the first image the “floor” is using an Edge Collider 2D (as proposed here) and the second one is using a Box Collider 2D.

I played with a bunch of different settings and colliders and can’t seem to resolve the issue!

Thanks!

Reposting Steel_Arm’s answer as he isn’t:

Also, what scale are you using? If you’re using a small enough scale, this will happen. Based on the size of that gap, I’m guessing your box collider’s scale is about 0.25. You may need to just scale up the size of your scene.
