Tick function summoning an invisible armorstand causes some of those armor stands to render transluscent for 1 frame

Im running a data pack i made to track the position of a snowball.
every tick an /execute command runs as every snowball to summon an armorstand with {Invisible:1} tag, run some other commands and then kill that armorstand.
But every now and then i see an armorstand render transluscent (as if you were looking at it in spectator mode) for just 1 frame...
