Problem is related to the plugin which created this user capability:
‘Nginx Helper | Configga.error’. Do you know to what plugin it belongs?
User Role Editor user capabilities ID as JavaScript identifires. URE replaced spaces with special place holder as you can see at ‘Nginx_URE-SR_Helper_URE-SR_|_URE-SR_Configga.error’. But I can even imagine that some_one will include into capability ‘|’ character.
I will include a fix for this symbol to the development version update ASAP.
