Trouble with buttons

Continuing the discussion from RetroArch Megathread:

I had to reset my RetroArch. During the process of inputting the following:
I got this:
Is this an issue?
Also when I went into Setting, Input, Hotkey Binds, and pressed B to initiate a toggle to change the button…,it brings up the screen for the countdown to change. However, I am unable to change the button to anything else except the Start button. Therefore, my Menu Toggle is either blank or linked to F1 key. Does anyone know why that is happening? Thanks in advance for any help.

Sorry, the first image was suppose to be an image of:
cd ~/.config/retroarch
rm retroarch.cfg
