Unable to update Mode setting

Current Mode Manager does not seem to have the option for changing settings of Modes.
For example right now I have a "Night" mode which is set to go on at 2300 hrs every day, I would like to change it is 0100 hrs. There no option in the Mode Manager to edit the setting for Night mode. I used to be able to do this in the past.
Is the a known issue? Or am I going something wrong.

Are you going into the modes from the settings option or the app itself? Modes are created in the settings option but times are set in the app itself.
