Rigidbody2D Player collider seems larger than displayed

Hey! I have an object with a BoxCollider2D and a Rigidbody2D, which is the blue box in the attached image. The black ground has a TilemapCollider2D and a CompositeCollider2D. For some reason, this is the closest the two objects will get to each other. As you can see, there is a noticeable gap about .015 units wide. The colliders bounds are as the sprites would suggest. Any help on this would be appreciated!

UPDATE

This has now started happening with another object, without a Rigidbody2D and the collider set to trigger. The presence of a SpriteRenderer does not affect the issue.
