Currently the first item is chosen (hard-coded).
Check why there is a duplicate entry.

The useEffect on 'extractionStatus runs the [html_file_loop](https://github.com/clowder-framework/CONSORT-frontend/blob/main/src/components/childComponents/CreateAndUpload.js#L57) again when the extraction is complete, as the extractionStatus` gets updated again.

Noticed this only when running in local/dev.
Might not be a bug. Did not notice this in prod. Will need to confirm before closing this issue
