Hello Nextcloud friends 
I hope you can help, I realise that as I’m not self-hosting Nextcloud that this might not be the right place to ask this question, but perhaps you can point me to the right place. I did ask on the Murena forums but they don’t seem to know the answer.

Summary of the issue you are facing:
I use the Murena.io instance of Nextcloud but mainly for hosting my calendar and tasks, I rarely use the webapp. I have a few calendars set up, some are tasks only and some are events+tasks. However, whilst looking at the tasks and calendar in the webapp something strange happened - now tasks that are in an events+tasks calendar no longer appear in the tasks webapp! When I look in the calendar webapp they are there, but when I go to the tasks webapp these calendars are listed on the left initially but then disappear! I’ve looked in settings but can’t see any filters I’ve got applied. Any clues please?
Steps to replicate it (hint: details matter!):
- I’m not sure what the steps were, but I did change a few settings in the calendar webapp relating to what is shown e.g. tasks, birthdays, week numbers.

I can’t see anything noteworthy in the Network tab, it looks like every calendar is loaded the same, both tasks-only and events+tasks ones.
