In this case, because the question is specifically asking about the forces acting ON the spring (as opposed to the forces from the spring & weight), the answer you’ve gotten is likely to be correct.
For one, we know that gravity is force that helps us keep things on the ground. In this case, the first down arrow is for gravity, which keeps the spring on the ground.
The second down arrow of “Gravitational Potential Energy” can also be termed as “Weight”, because our weight is actually just a measurement of the GPE that is acting on us! That is why our weight on the moon would be lesser than our weight on Earth, because there is less gravity and hence less GPE acting on us when we are on the moon.
I hope this helps answer your question, and I apologise if the diagram confused you as it was meant to depict the forces acting in both directions (misunderstood the question, sorry!)
