Incidents will show multiple URL's when you upload a file to multiple URL on Google Chrome, Firefox, Safari and Edge.
For example:

Endpoint Location: On the Corporate Network
Application: Google Chrome (macOS)
URL: https://example.com,http://example.com[view URL]
Release : 15.7, 15.8 and 16.0

If you upload same file to multiple URL in a single session of the browser, incidents will show multiple URL on all the website where same file is uploaded.
This is known behavior on macOS as per design.
