Celestial Boosts

My understanding was when you activate CELESTIAL BOOSTS, then all previous boosts are also reactivated. Boost #23 increases ambrosia production by 20%. Boost #6 increases ambrosia production by 10%. However, my ambrosia temple (level 11) which normally produces 440 per period, now only produces 528 (a 20% increase). It seems boost #6 has not been included. 

They don’t stack.
