calendars are constantly removed

https://confluence.atlassian.com/confkb/after-upgrading-to-team-calendars-5-3-calendars-don-t-appear-in-related-space-785451428.html

For some space i need to manually trigger the resolution:

" Go to  > General configuration > Team Calendars > Rebuild Space Calendars and click Rebuild. "

Some calendars are constantly being removed.

Is there a way to permanently fix this?

The above mentioned article also states:

You may also notice the following errors in the log:

 

EmbeddedCalendarsToSpaceMigrationTask.upgrade failed

Where can I find this log entries?

team calendars version: 5.5.4

confluence version: 6.7.2

The upgrade logs are in the atlassian-confluence.log files in the logs subdirectory of the Confluence Home folder. If the EmbeddedCalendarsToSpaceMigrationTask did not run you may be able to run it in the UI:

1. Open this URL in your browser: <Confluence Address>/admin/force-upgrade.action
2. Select EmbeddedCalendarsToSpaceMigrationTask
   in the "Upgrade task to run" dropdown list.
3. Choose Force Upgrade.

I look forward to hearing how it goes.
