When you are log time in the calendar, it is very hard to find the right issue if you have a lot of them. There are some helpers like favorite and recently but if you work daily on more than 20 Tickets this will help only particularly.
The other problem is that the Tempo search is also looking for closed tickets.
I would suggest to configure a tab by selecting a Jira Filter and you can search only for tickets in this filter.
With the filter function each user can define their own criteria for the search and can as example hide the closed issue from the Tempo search.
