Delete Phantom Process Monitor File List Entries

TLDR: deleting xlsx files created by BI Publisher within an Application Engine deletes the files in the process scheduler output directory, but doesn't delete them from PS_CDM_FILE_LIST so the entries still appear on the output page.

I have an application engine that creates a ZIP file of xlsx reports created using BI Publisher. If I delete those files using file.delete the physical files are deleted from the directory, but the process scheduler output shows 0 byte invalid entries. Can I just manually delete from CDM_FILE_LIST to get rid of them? Is there a better way?
