The last host state is not correct

CMK version: RAW 2.1.0p15.cre

HI all,

I notice a issue with my checkmk , not sure if it’s a bug. I tested turned off my winserver, the alert notification sent out. But the event is only showing “DOWN (Problem) “ rather than “UP→Down”. I checked the recent notification, it shows the lasthoststate is down, same as hoststate, but suppose the lasthoststate is up . any idea about this issue?
