Characters and alternate powers

DFiPL

I was just looking at the Nova red cover in my queue, and I noticed that the game details what his red does in both forms.

And that's not consistent. Iceman, for example, displays both effects for his blue, as does Spider-Woman for her purple.

However, X-23's green lists both, but only for 'this is what it does with your next cover in this power.' Wherever you are currently, all you see is the effects for "Holding Back," not "Berserker Fury." Ditto for Punisher (MAX)'s Punish/Army of One. Likewise, 4* Blade's Hunger/Bloodlust - you can see the effects with the next cover, but not both effects with whatever you've got.

Miles Morales doesn't display the effects for what happens when Hide & Seek becomes Surprise! - either for the current level or the next.

OML's alternate powers aren't displayed, perhaps because he refreshes his entire arsenal. 5* Jean Grey's From the Ashes converts, but there's no description on the character page of what Phoenix Force does.

There may be others I'm missing, but I think this illustrates the point - why is it that we can see what some characters' alternate powersets are without having to go into battle, and others we cannot?
