I've got a 360 video filmed with GoPro Fusion and stitched in Fusion Studio in 4K H.264

I've added the video to my timeline in Vegas Pro v17 and in order to blur some specific areas of the video I duplicated the video track and made my edits there.

Now I can't seem to be able to render as a 360 video anymore. The projects' video setting is one of the 360 options, but when I render it comes out as a black screen, and before that the presets are not indicating they would be 360.

Any thoughts? Am I doing something wrong?
