How Do I Delete the Default Task Calendar?

Operating system and version: Cloudlinux 7.9
Apache or nginx version: Apache 2.4.55
PHP version: 8.1
Nextcloud Hub 3: 25.0.3
Installed using Quick Install Wizard
Connecting using web interface (Chrome)

The issue you are facing:

I have a CalDAV sharing setup between Nextcloud and a number of Mac devices.

A self-created Default_Task_Calendar keeps showing up only on my Nextcloud Calendar Dashboard.

Steps to replicate it:

  1. Open Calendars
  2. Appears in left column
  3. Also checked all of my Mac devices. Doesn't appear there.
  4. When I try to delete it, it reappears.

Tasks is not one of my enabled apps.
