Wrong (Virtual) driver installed for SRT321 Thermostat!

This is weird:
When I include extra SRT321 Thermostat controllers in my Vera 3 UI5 network, they get the D_SmartVT1.xml devicefile!
But it is of course a physical thermostat, needing the D_SmartVT1.xml device file.

Problem is that although you can manually change the devicefile to the proper one, the list of variables is different, and does not change with it.
How comes, and how to avoid this???
