Ok, I just realised something weird. I have TI3 and its two expensions. I bought all of them new.
I have 18 yellow-bordered systems. That is normal.
I have 2 spiral-shaped systems. That is normal.
Apart from that, I have 9 SoTT systems (9+5=14, that is Ok). I have 23 SE systems (23+5=28, that is ok). And then I have... 35 remaining systems. Isn't it a bit too many ?
Here are the systems that should be in each box:

There is a Supernova tile missing in your count of the TI3:SotT tiles.
In my box there are five special systems (red border). Only the Asteroid field is missing the expansion logo.
That missing supernova tile is the special Muaat one, the back will have their symbol.
It doesn't really count, due to it never being part of the galaxy at the start of the game.
