Picade: keyboard config OK button not working

Each time I boot the picade I am asked to map the buttons & keys. I go through all buttons and once at the end “OK” is highlighted, but no matter what button I push it doesn’t save or go to the next step.
I can only go to F4 and enter cli.
I have updated retropie last night, and stil the same issue.
I can’t find the file to map the keys manually.
Strangely enough, when I push the buttons on the picade one button registers as “Esc”, another as “Alt”.
Regardless, ENTER doesn’t work when I get to the OK step.
Any help would be greatly appreciated!
