how to delete an old calendar?

[Kon]

After transferring from an old computer, 2 calendars of different vintage
showed up. How do I delete the old one?

Select the folder and press Delete?
Otherwise you'd have to provide some configuration information for us to
work with and tell us how exactly you transferred from your old computer.
When done correctly there is no duplication whatsoever.
