Mutiple island SHQ supplies problems

[coot33]

Not on the beta update.

I have an SHQ on 3 islands in this case. When the 2 main island were supplies by two different SHQ there was less problems. The islands are connected by airbridges. My units are not using the network to supplies themselves they decide to to take supplies farther away and get penalties even when there is hundred or thousands of points available.

Here the units on the right walk supplies from a road further away instead of using the airbridge or massive amount available logistic on it's hex.
On the left the units have the same behavior but they only get supplies from cities.

As observed here there is plenty of supplies and no bottlenecks. I'm very confused by the behavior.
Any one has any idea what is going on ? Why are my units not using the logistics available to them ?

There's an item in the Zone Orders screen to allow units to be supplied by the zone they're in. You should probably check that option. The other tab to check is the Items tab on the bottom, that will show which items are available in the zone. If there are no items in the zone, you can transfer them from the transfer menu.
