Thing about your emotions being leveled out so to speak is that its an effect that stops mind altering effects. Ainz's normal state of mind is what the ability is trying to preserve when he gets calmed down. Which means the reason we don't see our two vampire lolis get a chill pill is because the ability doesn't see their emotional states we have seen so far as mind altering effects. Shalltear's high and low moments we've seen so far are considered normal for her mindset so no need to calm her down. Same for Evileye, but Ainz's mind goes everywhere when his emotions get blown up and he loses focus alot of the time on the argubly more important things like fixing Shalltear or analyzing why its ok for him to grope Albedo all the live long day.
