File storage quota per project - 100% Usage despite all files being deleted

Gemini API
1

I am getting a quota error when using the Gemini Batch API related to the file_storage_bytes. I deleted all of the files 5 days ago, but the quota is still showing at 100% and I am getting this error on the API:

google.genai.errors.ClientError: 429 RESOURCE_EXHAUSTED. {‘error’: {‘code’: 429, ‘message’: ‘You exceeded your current quota, please check your plan and billing details. For more information on this error, head to: ``https://ai.google.dev/gemini-api/docs/rate-limits``. To monitor your current usage, head to: ``https://ai.dev/rate-limit``. \n* Quota exceeded for metric: ``generativelanguage.googleapis.com/file_storage_bytes``, limit: 21474836480’, ‘status’: ‘RESOURCE_EXHAUSTED’, ‘details’: [{‘@type’: ‘``type.googleapis.com/google.rpc.Help’``, ‘links’: [{‘description’: ‘Learn more about Gemini API quotas’, ‘url’: ‘``https://ai.google.dev/gemini-api/docs/rate-limits’``}]}, {‘@type’: ‘``type.googleapis.com/google.rpc.QuotaFailure’``, ‘violations’: [{‘quotaMetric’: ‘``generativelanguage.googleapis.com/file_storage_bytes’``, ‘quotaId’: ‘FileStorageBytesPerProject’, ‘quotaValue’: ‘21474836480’}]}]}}

I have double and tripe checked and there are zero files stored against the project now.
