Log Rotation: Based on rotate parameter deletion of archive log is not happening

OS: Linux 7
based on rotate parameter Log rotation is not happening. It means Based on rotate parameter log archive file supposed to be delete but based on cron job Archive is happening based on size but in the same time rotate is not working

Earlier Config file

/var/log/openldap/inst00/*.log {
copytruncate
missingok
notifempty
compress
daily
dateext
dateformat -%Y%m%d%H%s
rotate 10
size 300M
}
we added the dateformat parameter to come out from the confusion when multiple time archive file will generate in a day . But it seems when we added this parameter since than rotate is not working . so we modify the parameter as below but again the same problem we are getting after removing the dateformat .

/var/log/openldap/inst00/*.log {
copytruncate
missingok
notifempty
compress
daily
extension .log
rotate 14
size 300M
