Wrong Names for Entities via /say @e

I placed down a Command Block, put it on repeating and always active.

In the Command Block i wrote /say @e[type=!Player,r=10]

Then I placed down a Endercrystal and instead of "Endercrystal" it said "entity.EnderCrystal.name"

Then I threw a Lingering Potion near the Command Block. While it's normal its a Potion, but it should be "Lingering Potion".
When it was on the Ground instead of "AreaEffectCloud" it said "entity.AreaEffectCloud.name"

This works in Multiplayer & Singelplayer
