CalDAV calendars created from search queries show duplicated in "Calendar" panel

The problem

Calendar entities created by applying a search query to a 'master' calendar are are shown duplicated in the calendar view.

In the attached screenshot (fig. 1), three calendars pull from a single "Meals" calendar and search for all-day events prefixed with 'Breakfast:', 'Lunch:', or 'Dinner:' for respectively named calendar. The main "Meals" calendar isn't imported into Home Assistant, opting for the separated ones in it's place. Under the new Calendar panel, the "Breakfast" and "Lunch" calendar are showing "Dinner" events, despite not being actually active in their respective calendar. entities (fig. 2).

Expected behavior

Calendars should only show events for that particular calendar. entity.

Steps to reproduce

1. Add searchable event to CalDAV calendar (i.e. iCloud)
2. Create a calendar component from the CalDAV URL
3. Create child calendars using the search query (one positive, one negative)
4. Hide the parent calendar (do not import into Home Assistant)
5. Observe the calendar panel
6. Witness child calendars show all events from parents, and are not filtered.

Environment

• Home Assistant release with the issue: 0.110.x
• Last working Home Assistant release (if known): N/A
• Browser and browser version: Edge 83.0.478.37
• Operating system: macOS 10.15.4

That is the custom_calendars options of CalDAV?

This is an issue with the CalDAV integration, it should only return the events that match your search.

Same here, I have one Calendar containing info for 3 different garbage bins. Every calendar shows an entry under "My Calendars", but it shows all appointments ignoring the search criteria.

'Problem' persists in 0.110.2.

Version 0.110.3 still an issue.

calendar:
  # iCloud Calendar Definitions
  - platform: caldav
    url: !secret icloud_url
    username: !secret icloud_username
    password: !secret icloud_app_specific_password
    custom_calendars:
      - name: 'Holiday'
        calendar: 'Automation'
        search: '^(Holiday|HOLIDAY)'
      - name: 'Notice'
        calendar: 'Automation'
        search: '^Notice:'
      - name: 'Payday'
        calendar: 'Automation'
        search: '^(PayDay|Payday)'
      - name: 'PTO'
        calendar: 'Automation'
        search: '^(PTO|Pto|pto)'
      - name: 'Travel'
        calendar: 'Automation'
        search: '^(Travel|TRAVEL)'

Any of these have events, then they show for every other defined calendar as well. This might simply be an issue with the Calendar panel not handling multiple calendars? I have not dived in to debug it yet.

[onkelbeh]

Just browsed by, again, still the same with 0.114.3

[onkelbeh]

and 0.114.4
:-)

Confirm the same problem with duplicated events on the last version 0.114.4.

The same problem from other users here https://community.home-assistant.io/t/caldav-doesnt-generate-binary-sensors/204994/3

[yellowonblack]

The issue still present in 0.115.2 and also in the new Lovelace calendar card https://www.home-assistant.io/blog/2020/09/17/release-115/#calendar-card

[hassio-lars]

The issue is still present in 2020.12.7 in both the calendar panel and in Lovelace calendar card. Im totally unfamiliar with Github, but to me it seems there are no pull requests that address this issue?
