If you right clcik on them to get the properties, are they all the same?

Are you using the full editor? .

I went through all 12 instances and all properties for filename, Video, and Audio are the same

Did you apply scene detection or generate the rich video data from the import causing the 12 selections from one capture ? You can go up 1 level in order not to see those 12 selections.

I didn't apply anything. All I did was choose File | Import to bring the .TS file in. All the thumbnails are of the same image and same metadata.

I ran another test. I converted the .TS to MP4 via Handbrake. I then imported the MP4. Only one thumbnail appeared.

This issue seems to be specific to converting .TS files generated by Elgato.

Hello,

If you are getting duplicate thumbnails in the media room, it is because your .TS file has multiple audio streams.

If there are 3 audio streams in the .TS container, it is expected that there would be 3 separated videos, each with a different audio stream, in the PowerDirector media room.
