I've made this custom metro station so far using procedural objects, pedestrian paths and station tracks, as I wanted a curved station.

The bottom track here works just fine when i connect it to the rest of my metro network, but the top track simply won't let me add a stop to it. To be more clear, when I go into the add station mode, the little station circles appears on all 4 platforms. When I click on the bottom station track, it adds a stop there, but when I click on the top station track, it still goes to the bottom station track. I have no clue why this is the case. Maybe because they are too close? But I have seen stations in the game with tracks closer to each other. Any help would be lovely, thanks.
