As you can see, the mushroom has been rotated so that the higher part is angled towards the final platform, and the lower part to the previous mushroom. For reference, please ignore the box-collider; it's not being used, it's not even on the model or prefab(s) - it shouldn't even be visible as this prefab uses a mesh collider.
In addition, the duplicate mushroom in this position has been removed.
Issue is resolved!
