I asked this very same question so very long ago. The game has to go through the motions of an upgrade. Even though you have SY 3 researched, the game still has to up grade to SY 2 before it can go to SY 3.

You know, 1 before 2, before 3 etc. The work around should be that to go from a SY 1 to SY 3 should cost a hell of a lot more in resources than it would to go from a SY 1 to 2 then to 3.
