Resolution Note:
The Tilemap Component works in conjunction with a Grid Component. The Grid Component defines the layout of the Tilemap Component. The Tilemap Component will either use a Grid Component which is a sibling of the Tilemap Component or in a parent GameObject. Without a Grid Component, the Tilemap Component will assume that all the Tiles will be laid out in the same position.
When creating a Prefab of a Tilemap GameObject, always try to include a Grid Component in that Prefab, either on the GameObject of the Tilemap Component or on a parent GameObject.
