All my manually created calendars show up and two way sync is possible and fast, however the calendar feeds I am subscribed via Nextcloud to do not show up.

My todo list service (Todoist) supports one way calendar feeds which I imported to my Nextcloud calendar, but these calendars do not show up in KOrganizer. I was able to setup my iPhone using the same CalDAV link I used with Nextcloud, and I am able to see all the subscribed feeds normally on it. I also tried naming a custom calendar in the same scheme as the calendar feeds, but it showed up fine.

Has anyone encountered this before? If not, could someone point me to the log files that might show what is going wrong?
