Submit a Ticket to Microsoft Online Support
Since this filtering malfunction is a known tenant-level issue within the new Microsoft Lists experience, it requires direct backend investigation by the Microsoft support team.
Forum support teams do not have the necessary permissions to inspect specific tenant environments. To resolve the filtering issue permanently, an administrator must escalate the problem to Microsoft Online Support.
Log in to the Microsoft 365 admin portal using an account with administrator privileges.
On the left-hand navigation menu, click on 'Support' and then select 'Help & support' or 'New service request'.
Describe the calendar view filter issue clearly. Include the affected list URL, specifics of your view configuration, the number of affected users, and your tenant details.
Detail the exact steps users take when the filters fail to apply, and submit the ticket for Microsoft engineers to investigate.
