I just downloaded Electrum and when it asked me what kind of wallet I wanted, I accidentally pressed the kind where I need two machines to use it. I didn't understand that this was the kind of wallet I chose until after I entered the seed.

There is no discernible way to cancel this action and get back to the original screen that asked me what kind of wallet I wanted. There is a cancel button. This quits Electrum, and when I reopen it, I am back on the same page. There are no top menu options. I reinstalled Electrum twice and it still reopens to this screen.
