Bug: saving CSV of files

[SeanLeRoy]

From Jianxu:
When I select a consecutive list of files (e.g., click while holding Shift), and then select “Save Metadata As … CSV”, everything is fine. All information is saved properly.
When I select a random list of files (e.g, click while holding Command / Ctrl), and then select “Save Metadata As … CSV”, then only the column names are downloaded. It is an empty table …

Notably this seems to only be an issue with uploaded data sources.
