nnn file manager not allowing me to press r key for batch rename

I am using Arch and bash. All packages are current and up to date. I am using the nnn file manager. I go into nnn and make a selection of 3 files by pressing the space bar while over each of the three files. This is how files are selected in nnn. Then I should be able to press the r key to batch edit the selected filenames in neo-vim. When I press r I see failed! in the bottom left hand corner of the terminal. This is a rapid and very useful way to re-name files in a dir. It was working and for some unknown reason has stopped. ps nnn has no .config file to speak of and is set-up in .bashrc. Within .bashrc I have the following: # setup bookmarks in nnn export NNN_BMS='s:/home/$USER/linux_config' # set nnn editor NNN_USE_EDITOR='/usr/bin/nvim' export NNN_OPTS="H"
