I need to change the armor stand placement altogether so I unchecked invulnerable and immovable to destroy it and take the items, but the armor stand suddenly paced through the block it is standing on and vanished completely, I tried to check underneath and it's gone, all the way to the bedrock, no signs of it at all

I've had that happen too, the armor stand can sometimes glitch into the blocks it is standing on and will then just fall through the world until the armor stand entity dies in the void below.
The thing is Armor Statues is more or less a client-only mod, it does not change any behavior regarding the armor stand entity. It only allows for more conveniently editing properties which all already exist in vanilla.
So I'm kind of assuming this comes down to some quirky vanilla behavior essentially...
