Units not being sent from Staging Areas!

I have noticed a few times and it just did it to me again! Where I send a Unit that I know is at the staging area and the ARR sends a Unit 2 1/2 hours away instead! So I phisically have to Click on the staging area, find the vehicle I need and then manually send it from there! The ARR should be sending the closer units that are at the staging area! It's not ALL vehicles, just 1 or 2, but it is such a pain to then have to find them all manually!
