Describe the bug
A clear and concise description of what the bug is.

For a qnn recipe, there will be multiple models in genai_config.json. But if I enable "profiling_level": "detailed" and "enable_profiling", the second "profiling_level": "detailed" will not work.

                    "context_ctx": {
                        "filename": "context_ctx.onnx",
                        "session_options": {
                            "provider_options": [
                                {
                                    "qnn": {
                                        "htp_performance_mode": "burst",
                                        "htp_graph_finalization_optimization_mode": "3",
                                        "soc_model": "60",
                                        "profiling_level": "detailed",
                                        "profiling_file_path": "qnn1.csv"
                                    }
                                }
                            ],
                            "enable_profiling": "op1"
                        },
                        "run_on_token_gen": false
                    },
                    "iterator_ctx": {
                        "filename": "iterator_ctx.onnx",
                        "session_options": {
                            "provider_options": [
                                {
                                    "qnn": {
                                        "htp_performance_mode": "burst",
                                        "htp_graph_finalization_optimization_mode": "3",
                                        "soc_model": "60",
                                        "profiling_level": "detailed",
                                        "profiling_file_path": "qnn2.csv"
                                    }
                                }
                            ],
                            "enable_profiling": "op2"
                        },
                        "run_on_prompt": false
                    },

After run, op1.json op2.json and qnn1.csv exist, but no qnn2.csv.
