I am making a teamspeak server and i am having issues when adding server groups. I have browsed through the internet for days trying to find a fix for this and tried all solutions. No results...

This occurs to all groups that try to be added.
All group are highlighted (so it looks like you can add them) however, when that group is selected, this error is thrown: insufficient client permissions (failed on i_client_needed_permission_modify_power)

Below is a list of the permissions between 2 groups.

Deputy Chief
Add Power/Needed Add power: https://gyazo.com/d850a630603d0389b6f5dafcb1ba5d74
Remove Power/Needed Remove Power: https://gyazo.com/4306a20c964c7a6d2932bf7098242d81

Add Power/Needed Add Power: https://gyazo.com/f5bba0f90f484cd54ffd560c6bafabd8
Remove Power/Needed Remove Power: https://gyazo.com/238aaeb7764a53b04091ac8fe76adf46

As the error thrown is i_client_needed_permission_modify_power, i checked for this value. Here is what it is:

Deputy Chief
Needed Client Permission Modify Power: https://gyazo.com/9ee874bddbb96273eaffea77ebaf28af
Client Permission Modify Power: https://gyazo.com/aa971a793719c8c828cb01dd55e9c6b6

Needed Client Permission Modify Power: https://gyazo.com/7949f1c970fbbc2c9e10b216759758ef
Client Permission Modify Power: https://gyazo.com/3e4aa54bbec4f93d570b414c05580257

My intentions are to simply enable the adding and removal of the Constable tag when you have the Deputy Chief tag.

I appreciate any help, thanks.
