Premiere Pro iPad uploads extra blank long videos when posting YouTube Shorts

When exporting a vertical video from Adobe Premiere Pro on iPad using Direct Upload to YouTube Shorts, the Short uploads correctly. However, Premiere also creates two additional long-form videos on the same YouTube channel. These extra videos are blank, stuck processing/loading, and must be manually deleted every time.

Expected result: only one YouTube Short is uploaded.

Actual result: one Short uploads correctly, plus two incomplete long-form videos appear.

This happens every time. Deleting the extra videos does not affect the Short, but requires manual cleanup after each upload.
