Channel Posting Privileges

I try to add under CP Home > Members > Member Groups > Edit Member Group some Channel Posting Privileges to the Member Group ‚Admin‘.

So they should edit, add and delete new categories as well the ’Super Admin Group’ can do. There are some radio buttons for ‘Can edit and add new categories‘ and ‘Can delete categories‘, which I turned both on ‚Yes‘, but they do not work as expected.

If someone of the Member Group ‚Admin‘ would edit categories under CP Home > Publish > Edit Entry they get the following error:

Thanks for Hints!
