When there are already a few entries with different categories, I tried to search for all entries of only one category. After searching for the category "work" in the search field, there are no entries listed and when you go back to the weekly view of the calendar all previously created events are not visible anymore (Windows 10 Firefox, as well as Chrome). A feedback is appearing in the left lower corner: "No dates in the searched calendar available".

Steps to reproduce:

1. Create some events with different categories: work, family, personal
2. search in the search field for one particular category
3. go back to the weekly view of the calendar

Actual results:
no entries are visible anymore

Expected results:
when searching for "work" entries, the entries are appearing and not "deleted", and they are still visible in the calendar when you go back to your weekly view
