I'm recreating Portal in vanilla Minecraft and now I have the Problem, when I'm summoning an Armor Stand with this Command:

execute unless entity @e[tag=cube1,type=armor_stand] run summon armor_stand -332.07 162.00 -19.58 {Invulnerable:1b,Invisible:1b,Tags:["prop","abletopickup","cube1","cube","ismakingsound","hashitbox"],DisabledSlots:4144959,Rotation:[373F,0F],ArmorItems:[{},{},{},\\\\\{id:"minecraft:iron_hoe",Count:1b,tag:{CustomModelData:1}}]}

- Command is running, each tick in a function

It should only summon a new armor stand when the previous armor stand has died

But when I log out of the Game and rejoin the World the entity gets summoned 3 times, what should not happen
