Describe the bug

I am currently attempting to batch delete 50 traces using pagination via the Langfuse API. Although the bulk deletion endpoint (/api/public/traces) returns a 200 success response, the traces remain visible in the UI and are not removed as expected. even after 24 hours, the traces are still present. I am following the Langfuse API documentation for bulk deletion (https://api.reference.langfuse.com/#tag/trace/delete/api/public/traces) and using the recommended endpoints, but the issue persists. I am using the self-hosted Langfuse OSS version 4.10.0. I am experiencing a similar issue with deleting single trace from API /api/public/traces/{traceId} it is still showing in UI Could you please provide assistance or guidance on how to resolve these issues? I tried from UI , where it should "Deletion is asynchronous and traces will continue to show for 24 hrs" . Even after 24 hrs the traces are still shown in UI
