I encounter an issue that, when trying to update the group members' flag (such as manager flag, notify flag), those changes were unable to save.
There is no error message after saving, it actually returned save success, but the flag remain unchange.
Adding and removing group member are functioning normally, editing any other field value of group also functioning normally.
There is no error in the stdlog while I update the flags.
This is a fresh installation of SDM 18.104.22.168. without any customization.
