That sounds like the same issue, especially since it persists several days later and affects estimated usage.
If both removing the vector store file object and deleting the underlying file object still leave it visible/counting in the vector store. Like I already recommended in the post above, that this seems worth escalating to Support with the vector store IDs, file IDs, timestamps, API responses and screenshots.
Maybe @OpenAI_Support can also take a look here, but they would likely still ask everyone affected to open a Support ticket so they can investigate the account/project-specific details properly.
I also came to think of a separate issue that still could maybe be connected. There have also been separate reports of PDF/DOCX files failing during vector store processing/upload, which I could reproduce on my side with a PDF. I don’t know if that is connected to this deletion/removal issue, but both seem to involve vector store file processing/state.
