text displays wont delete themselfs

and the backrounds of the text displays are showing

So your 2 killing methods both are done a little incorrect, you dont delete entities it should be

kill {_d}

And the other killing method i think needs to have a sorting method

minecraft:kill@e[type=text_display,limit=10,distance=0.5,sort=nearest]

And about the background color what i always do is

set display text background color of {_d} to bukkitColor(0,0,0,0)

[proven oracle]

delete %entity% is a thing. It kills them instantly without the death animation/poof particles

[snow forge]

ah didnt know that, but even then wouldnt that try to delete the variable {_d} or am i wrong

[proven oracle]

Might need entity in for that case

[violet aurora]

works perfectly with
kill {_d} and set display text background color of {_d} to bukkitColor(0,0,0,0)
