International zone exits not being recognized

Hi everyone,
I’m currently working on building an airport in sandbox mode, and while trying to get the international zone set up, it is not picking up the exits. Does anyone have any ideas as to why this is happening? I have tried pathfinding passengers out of the international zone to no luck, so I know that would mean that it won’t work when I actually start bringing flights into/out of the airport.

Try to remove the last line of international zone under the passport boxes, otherwise try to save and load the game.
