Nexus 5548UP wrong logging order in log file

We have a Nexus 5548UP switch, it logs required events, however when show logging, the logged events is not displayed in proper order. Starting April 23, 2019, the logged events were inserted into the logfile from the top. Does anyone encounter same issue? I searched Cisco bug no luck.

Re: Nexus 5548UP wrong logging order in log file

This is bug CSCui73960 which states "Log messages in local logfile buffer are not sorted properly based on their timestamp. The "sort" pipe option sorts them better but still not in the fully sorted way."
