Certain commands within functions don't work on things in other dimensions

from main tagged with #tick:
#death and respawn effects
execute as @a[tag=

{DeathTime:0s}] at @s run function g3mine:main/deatheffect
execute as @a[tag=died,nbt={DeathTime:0s}] at @s run function g3mine:main/respawn
#height as score and test voidfall
execute as @a store result score @s height run data get entity @s Pos[1]
execute as @a[scores={height=..-64}] at @s run function g3mine:main/voidfall

Voidfall:
teleport @p 0 255 0
setblock 0 255 0 end_portal
say i fell into the void somehow
effect give g3david saturation 255 1 true
tag @s add voidfall
attaching respawn and deatheffect, too long to paste here,as well as the main and voidfall
