Setting frequency by the remote control protocol problem

[RicconSt]

Hello, everyone. If I set the frequency with the mouse on the screen, then everything is fine. When I give the command F 14450000, the frequency is set, but with a offset relative to the center by 432 kHz. Why is it so and how to set the frequency without offset?
And why is the maximum sensitivity only in the 200kHz band? I use Sdrplay and in SDRUno for Windows, I see a band up to 10MHz
