Run "3dinfo -VERB" on that dataset to verify
what the sub-bricks are, just to be sure we
are not having moot conversation.

But if it were output by 3dttest++, then volume
0 should be the mean of the input volumes, not
something to threshold on. The labels showing
SetA_mean suggest this.

Anyway, what does 3dinfo show?
