Start by reproducing the problem in the Activity tab with a newly uploaded PDF, comparing its broken image with an older PDF entry whose icon still appears. Read the activity app's frontend handling for file icons and inspect the browser output while loading the activity overview. Done means newly uploaded PDFs display their PDF symbol instead of a broken image.
