Virtual Bench Pro 4 Saving Spec File

I tried generating a configuration for a DC/DC Converter without being connected to the Converter
In Virtual Bench Pro 4.0 I created a new Project. The default voltage is 3.3V. If I change that to 4V and save the file it wont be saved. When opening the file again it reverts back to 3.3V.
Even if I use the “Save as” option it does not save the desired value.
I suspect that only values that have been written to the device will be saved. But I want to create configurations without connecting to a device.

I tried a few things and came up with a solution.
You have to press the “Write RAM” button even if there is no dongle connected.
After that the values are saved to the file correctly.
