Upgraded Passive effects missing


While trying to optimize my playstyle with my Enhancement Shaman, I realized that certain passive ability effects are not present.

For example: The ability Chain Lightning gains a passive at lvl52 that reduces the cooldown of Crash Lightning when used with Maelstrom Weapon does not show in my Spells and Abilities tab anymore…

It only sparked my interest after seeing my Crash Lightning cooldown get reset during combat and I had to google to find out what was causing it.

Any ideas on how to see all the passive abilities of the class?
