Not sure if im missing anything but there are two missions that seem impossible to pass right now

1) Gateway to Elysium - Requires 6 Centers of Trade of the Bay of Elysia but there are only two
2) Control Adronika - Requires 4 Centers of Trade in Adronika but only 3 exist in game.

Is there supposed to be events or decisions to create more centers of trade?

There are "Favourable Trade Locations" represented by a modifier, which is also visible on the trade mapmode, scattered around those regions. Those can be turned into a Center of Trade. You can see exactly how to turn them by hovering over the modifier.

I think I also wrote a tooltip about this into each mission trigger that requires you to know about this mechanic.

Thanks Scurek! This worked.
