barbarian rage power info not predictive

level 2 barbarian choosing a rage power ("feats abilities" -> "class abilities" )

when a Rage Power is selected on the left the details in the info pane (lower right) reflect the status quo rather than the effect that adding that rage power would give. I find this confusing.

eg:

Guarded Stance Type: RagePower
Description: You gain a +0 dodge bonus to your Armor Class against melee attacks for 0 rounds. Activating this ability is a move action that does not provoke attacks of opportunity. Benefit: You gain a +0 dodge bonus to your Armor Class against melee attacks for 0 rounds. Activating this ability is a move action that does not provoke attacks of opportunity. Source: Paizo Publishing - Core Rulebook, p.33

I mean, "+0" why would I want that?

once the power has been added and the power is selected in the right pane the correct comptations are applied.
and the info pane shows the correct result.

It would be nice if when a selection is made in the left pane the info pane could be computed under the
assumption that the power has been added
