Soul of Emancipation doesn't let you deselect a target

[bold oasis]

I played [[soul of emancipation]] and accidentally chose a target i didn't want to choose. it wouldn't let me deselect the target. instead it "chose" that target as many times as i clicked on it.

When Soul of Emancipation enters the battlefield, destroy up to three other target nonland permanents. For each of those permanents, its controller creates a 3/3 white Angel creature token with flying.
