Can't reset birthday reminder after migration in thunderbird

I’ve migrated from NC 9 to 10. I’m using a calender in thunderbird with the sogo connector 31.0.3. There is another calender containing the birthdays from the contacts (the link is https://mydomain/cloud/remote.php/dav/calendars/Stefan/contact_birthdays/).
If a birthday reminder pops up in thunderbird I can’t close it. There are no problems with reminder from the normal calendar.

Same here, using emClient and davdroid. Remiders were automatically added during migration from NC 9 to 10 and can’t be edited/removed. Both clients show frequent errors during the birthday calendar sync. The sync of all other calendars works fine. Is this a bug of the expected behaviour?

@teneco @aestheticus
did you have also two calendar entry’s like me?

Hi Micha,

No, just one; all from the contacts - and all with reminder enabled.

Same here. I’d also like to have an option to NOT create VALARMS for contacts. I opened enhancement bug Bug 1505.

I have exactly the same bug here.
Here is my error console log in Thunderbird 45.3.0 / Lightning 4.7 :
