Why the SEL (System Event Log) on unmanaged BMC device be cleared after pressing “Clear Event Log with BMC” button of QSM UI?

This is a known issue of QSMv1.0.2 and v1.0.4. After pressing the button, “Clear Event Log with BMC”, on Events page of QSM, the SEL on all unmanaged BMC devices will also be deleted. Please backup SEL that you think as important before click button, “Clear Event Log with BMC”.
