please get rid of that invisible one
The invisible one isnt visible like that in-game, you only know if it's existence if you select it. Invisible paint is
very useful and really the only option if you want to spawn light in mid-air (because setting rendering off also sets light off). What ever you do, do
not get rid of the invisible one.
You can surely move it elsewhere if you want, but do not even consider getting rid of it.
