Sorry but this is private

Please explain your issue. How do you trigger it?
Every Group i created works perfect and as expected, but the ONLY group that doesnt work is the "Owner" group because it got ''

How do i fix this?

Are there any errors in the console? Please use: https://pastebin.com
No Erros for this PLugin spotted
