Teleport summoned Entities in the same tick.

I made a impulse command block connected to a line of chain comamnd blocks.
Because the chain commands execute in the same tick, and for example the first command was:
/summon ArmorStand ~ ~1 ~

and the second was:
/tp @e[name=Bug] ~1 ~ ~
When powering the impluse - the Armorstand will be spawned - but not be teleported 1 block at the x.
After quiting the world and rejoining the armorstand is at the right position.
THIS ONLY HAPPENES ON NOGRAVITY:1 ARMORSTANDS

What I expected to happen was...:
The Armorstand will be summoned and then teleported.

What actually happened was...:
The armorstand was summoned and Teleported(When i tped to him i was tped +1 block at the x) but the armorstand looked like it still was in the first position.

Steps to Reproduce:
1. Place block like that:
I C1 C2
I = Impulse
C = Chain
2. Command in C1 = /summon ArmorStand ~ ~1 ~

3. Command in C2 = /tp @e[name=Bug] ~1 ~ ~
4. Power I.
