Peak obtained MS2 scan but no peak observed in product ion scan mode

Today, I encountered an intriguing issue with our instrument. Specifically, it appears to be operating as expected during the MS2 scan mode, precursor ion check mode, and MS2 Sim mode, showing a clear and well-defined peak for the analyte. However, I must bring to your attention that we are experiencing a peculiar situation during the product ion scan and MRM mode, where no peaks are being detected.I kindly request your expertise and insights on this matter to help us resolve this anomaly. Your assistance in troubleshooting this issue would be greatly appreciated.
