Police / Ambulance Station - Unable to Swap Vehicles

Hi all,

Something small I've picked up on, when attempting to move vehicles and swapping them between stations with others, it doesn't work and displays a "There is no room for this vehicle in this building" error similar to when you 'shift here' and there are no available spaces. This is for both Police and Ambulance Stations, fire stations work fine.

Issue has been around for some time, but never actually got around to faulting it.
Web Browser is Chrome, but same issue across Edge and IE.

Thanks
