Editing filters always changes status to Expired unless manually set each time

**Describe the bug**

Editing a filter always changes the status of the filter to "Expired" unless you manually specify the status. It does not preserve the current/already selected status.

- Which site version: 2024.04.19.5145730
- Which instance: https://emacs.ch

**To Reproduce**
Steps to reproduce the behavior:
1. Go to Menu > More > Filters
2. Click the edit icon for one of your filters.
3. Click save
4. See the status changed to expired

**Expected behavior**
Filter statuses should retain what is already set, not default to expiring the filter.

**Screenshots**

As you can see in this filter the status set is "Never Expires"/Never. But unless I manually set a new status every time it will be set to expired. Even when all I want to do is add a keyword. This to me is a bug.
