There are 2 things :
The destinations using stations are not marked as complete, that's perfectly normal as they will be computed at the end. The best use of station will automatically be made, in case the station can use multiple opponent routes. I added a (?) icon next to the destinations, when you create a station, to make it a little clearer.
The game only had 1 day of beta, so it might still have some little bugs about this, as it is the most complex part of the new things added to this version. If you're 100% sure about the fact that a station should have worked but didn't, at the end of the game, then please report a bug with all details. I've noticed at least one bug report about station that seems real, so I'm investigating it.
