Neco-Arc vs Specific Character Victory Demos not unlocking

[soundtoxin]

I'm going through getting everyone's character-specific Victory Demos, I have 80% of the total demos by now and it's been going pretty well. I get the 3 and 10 win streak ones at the same time. I'm just doing VS Mode on lowest difficulty on single round mode to make it faster.
For some reason after playing my 10 matches as Neco-Arc, I only unlocked Generic Victory Demos and the 3/10 Streak ones, despite specifically fighting the characters I'm supposed to, listed under the Achievement screen.
If it matters (god, I hope it doesn't), I was playing with the Neco-Ciel color palette. Is it possible that made it not roll any of the specific ones? Did the other seiyuu not voice the character-specific victory demos, taking them out of the table of possible demos?

That really was the problem. Playing as default color palette/voice I got the demos now.
