I am playing as Vaulters on Endless difficulty and I have noticed that all my systems have ridiculously high approval 'from planet'.

After investigating the issue and some testing I came to the conclusion that the Level 3 system upgrade using Lost Cities luxury grants approval bonus (+2 approval / pop) multiplied by number of planets in the system.

See screens of a 5-planet system on a turn before system upgrade is completed and next turn after it is completed - approval 'from planet' jumps from +57 to +377 - a whopping +320 change (which is +10 per pop as there is 32 people there). I conclude the bonus is dependent on number of planets, because I did test on 4 and 3 planet systems and the approval contribution is +8/pop on 4 planets and + 6/pop on 3 planets. 

Is this how it is supposed to work? It seems way too good. 

Vanilla calculates +2 happiness per population, then adds that number to the base planet, so its getting multiplied twice

Here you are. The upgrade is built in Andromeda.

Most of my systems have the level 3 upgrade already, so you can see that in all of them the approval from planet is very high.

Then maybe there's some other mechanic than multiply by number of planets, but "multiplied twice" still doesn't reconcile the numbers, as I'm not getting +4 approval / pop, but +10 (Andromeda), +8 (Iceland) or +6 (Triime).

But why is it added twice?

This is the effect of the luxury, as you can see it adds 2 per population to RecipeIngredientEffectTier2Luxury14

        <Modifier TargetProperty="Happiness"                                                Operation="Addition"    Value="$(RecipeIngredientEffectTier2Luxury14)"                  Path="ClassColonizedStarSystem/ClassColonizedPlanet"/>

This is where the value is added to happiness in the star system. You can see here that it's adding to the happiness of each planet in the star system, which means each pop on that planet will get that happiness.

Ok, I believe it does that, however is this intended or a bug in itself (that is part of what I observed)? Because it certainly is not in line with the upgrade description which says +2 happiness/pop period.

This isn't intended. the first bit of code shouldn't exist because the planet value already is per pop.
