Calendar app 2.1.2 shows not recurrence dates

Hello together.

I try to import ical data in the calendar app, but not all of them is shown in the calendar. So I hope I can get some help from you.

I have imported a ical calendar file, that contains some VEVENT’s with RDATE;VALUE=DATE: followed by a list of dates. The file was imported without any error and if I export the calendar, the result contains all data. But in the calendar app no entry for events with RDATE proptery is shown.
All “simple” events from import file are visible in the Calendar app. Also events, that contains a RRULE property. I have made some tests with different formats, but without any effect.

Example List:
BEGIN:VEVENT
UID:DE-IF-KARFR
DTSTART;VALUE=DATE:20060414
DTEND;VALUE=DATE:20060415
SUMMARY:Karfreitag
RDATE;VALUE=DATE:
20070406,20080321,20090410,20100402,20110422,20120406,20130329,20140418,
20150403,20160325,20170414,20180330,20190419,20200410,20210402,20220415
DTSTAMP:20000101T000000Z
END:VEVENT

Example Multiple RDATE:
BEGIN:VEVENT
UID:DE-IF-KARFR
DTSTART;VALUE=DATE:20060414
DTEND;VALUE=DATE:20060415
SUMMARY:Karfreitag
RDATE;VALUE=DATE:20070406
RDATE;VALUE=DATE:20080321
RDATE;VALUE=DATE:20090410
RDATE;VALUE=DATE:20100402
RDATE;VALUE=DATE:20110422
RDATE;VALUE=DATE:20120406
RDATE;VALUE=DATE:20130329
RDATE;VALUE=DATE:20140418
RDATE;VALUE=DATE:20150403
RDATE;VALUE=DATE:20160325
RDATE;VALUE=DATE:20170414
RDATE;VALUE=DATE:20180330
RDATE;VALUE=DATE:20190419
RDATE;VALUE=DATE:20200410
RDATE;VALUE=DATE:20210402
RDATE;VALUE=DATE:20220415
DTSTAMP:20000101T000000Z
END:VEVENT

Other applications (Thunderbird Calendar) shows all recurrences. The File was also checked with an ical validartor (https://icalendar.org/validator.html)

I hope you can point me the right direction to get the calendar entries visible.
Many thx in andvance.

Why haven’t you fixed the syntax errors in your examples if you’ve checked it using the iCal validator? In the both examples at least the VCALENDAR, PRODID and VERSION tags are missing :wink:

Your issue might be related to the following unsolved issue.

@j-ed: Sorry, I haven’t add the whole calendar file. It is only a snipped from file to illustrate what I have uploaded to the Calendar.

Same with new version of Calendar app 2.1.3.
If necessary I can provide the imprted iCAL file and also the export of this Calendar from NC Calendar app.
