When searching for "norwegian reggaeton" I get the original video result as #3, while the first result is some "reaction" video.

If I change sorting to "Views" and "Most first" I get original video as #5
In regular search videos sections show correct order of videos (original is #1).

I expected:
1) First result is original video in 100% of cases
2) than all live/cover variants of the song
3) only the last ones should be "reaction to" content (if there would be a setting to remove reactions altogether I'd do that)
P.S. Google in Video search makes original video #1, Bing doesn't show original video at all, maybe that why in your results it is on #3, but imho this is unacceptable.
