The screen snapshot below shows that the Exploit Population executive order says "All planets outputs +200% for 5 months."  The key word in that sentence is "All".  However, when you click on Exploit Population, you have to select a planet that will be the target of the executive order.  After choosing a planet, that planet shows the increased output, but no other planet does.

I suggest that you either change the wording of the Exploit Population executive order to say something like "Increaase the outputs of a single planet by +200% for 5 months." or actually increase the outputs on ALL planets as it currently says.
