Bug Calendar search ignores the deleted date filter

Hello,

In the web Agenda (App Suite), a search (e.g. "ufc") shows a date filter "Before [date]" that I did not set myself : 1st May 2026. When I click the X to remove it, the search stays limited to events after this start date — older events do not appear in the results.

I tested this in a private/incognito window (so no local cache involved): same behavior.

I confirmed my events before 2026 do exist and are visible via Thunderbird (CalDAV sync), going back to at least 2022. So the problem is located in the web interface's search, not in the data itself.

Workaround found: removing the date filter (clicking the X) is not enough. You have to manually set a new, wider filter instead — e.g. "After 01/05/2022" — which forces the search to actually cover that period. This suggests that deleting the filter chip does not properly reset the query sent to the server; only explicitly overwriting it with a new date range works.

Screenshots attached.

Could you confirm whether this is a known bug, and whether a fix is planned?

Thank you.
