Can't see proxies generation

Hi all,
I have just installed Davinci Resolve 17 cause i switched to a new camera.
I was trying to make proxies to work faster, but in the menu list i have just the "optimized files" option.

Do you know how to solve this?

Thank you very much!!
Mauro

In the Media Page, when right-clicking on a clip (or clips), there is no "Generate Proxy Media" ?
