[BUG]Elsa 3.1.3 uses a visual designer to implement workflow approval. When a node approval is rejected, the process cannot return to the previous node or the original node?

You can connect the Reject outcome to a previous node of your choosing.
That being said, the Fork activity will execute both Reject and Approval, so your workflow will probably not accomplish your goal. Instead, you might want to consider using the Switch (flow) activity.
