It's a core node so is under the main node-red global install (as you have shown). So if you are using Node-RED pre v0.19.4 you do need to use sudo to remove it from the correct place
cd /usr/lib/node_modules/node-red/node_modules
sudo npm uninstall node-red-node-rbe
then you can re-install it from the palette.
If using 0.19.4 or more recent - you can just install a newer version locally and we will ignore the core one
cd ~/.node-red && npm i node-red-node-rbe
PS- Always worth checking what was actually changed... in this case just the Japanese locale file... so unless you need it - don't worry about it.
