Command Block @e not in

The command blocks still say type:
@a for all
@p for nearest
@r for random

but when you added the @e it was not added yet

That is it. By the way I put it as a bug because nothing else came up and I decided to keep it as a bug because it has been bugging me ever since you added it.

Thanks Mojang.

Oh and last thing I have sent you guys an email and sent a bug report about how my Minecraft was blinking tell me if you can fix that because ti si pissing the crap out of me and it is bugging my friends too because this site classified it as "duplicate" so other people are suffering about this too. If there is any way to fix please do and thank you!
