"aureport -x --summary" shows -> /usr/sbin/sshd;61b30d72 (deleted)

On one of the machines running Centos i.e.

cat /etc/redhat-release 
CentOS Linux release 7.9.2009 (Core)

i found something strange by the command aureport -x --summary

 aureport -x --summary

what does "61b30d72 (deleted)" means

rkhunter does not show any warrning or susspect files! i.e.

rkhunter --update --propupd
[ Rootkit Hunter version 1.4.6 ]

and then

rkhunter -c -sk

!!!all green!!!

what 61b30d72 means?

It means that the executable file /usr/sbin/sshd which the report line refers to has been deleted between the time of the audit log entry and the time of the report. The most probable cause is that it has been replaced by an update. This explanation is supported by the fact that there is another line /usr/sbin/sshd without the mention deleted which would refer to the updated executable which was present at the time the report was created.
