[General] "Specific Target Damage" on Thunder Clap?

[Kyrbi0]

Question in title: Apparently both the Mountain King's Thunder Clap and the Neutral Hostile/Creep Slam have a field that reads "Specific Target Damage". Both times they are zero-ed out. Since they are both no-target AoE abilities, I wonder how it could even tell what specific target to pick.

I tested out a modified version with max (~999999) damage being dealt, thinking it would instantly kill whoever it decided was the Specific Target... Little surprise, nothing untoward happened. Spell was cast & dealt only standard AoE damage as expected. :< (this was on Thunder Clap).

Thoughts? Just another useless oddity?

Bump. Also, correction; (Neutral Creep) Slam has a field labeled "Extra Damage to Target".

Some abilities has useless non-working fields.
The Thunder Clap has the same fields like Frost Nova, but Thunder Clap doesn't detect the ability target.

Is there a list of all the spells with useless fields?
