Clear Morph Targets node does nothing?

I’ve imported a skeletal mesh with several morph targets and I can set their values using Set Morph Target.

Now I want to reset all morph targets back to zero.

I tried using Clear Morph Targets, but that didn’t seem to do anything. Does Clear Morph Targets mean something else?

What I’m currently doing is using Set Morph Target to individually set each morph target back to zero.

Is this the best way or am I missing something?
