OpenTTD Problems • Depot button not working

There is a button in depot for all transport types that reads "Autoreplace all [type] vehicles in the depot".

Here is screenshot:

I understand that (auto) "replace" and "renew" are 2 different things, replace upgrades a vehicle to different newer type while renew does it to same but fresh vehicle. So according to the tooltip of this button it should replace a vehicles in depot with new modern type, e.g. bring up vehicle replace window.

Problem however is this button does nothing to vehicles in depot regardless if vehicles are stopped or not. Is the button functional or broken? and if yes what exactly does it do? and how it works or why it doesn't?
