Krename on reboot reappears

Hello
This is only a recent thing only noticed this happening in the last few months
when using Krename and finished then I quit Krename
then doing other things not with Krename
and it is closed when rebooting,
Krename is the app only one that will open an instance (sometime as many as times opened during last session) on reboot
Is this a thing for Krename now and if it is
would maybe going to different renaming app what do you suggest ?
Any help appreciated thanks in advance
