SD-WAN unable change password after changed vmanage-mdoe

[chocolate2395777]

Hi All, 

I have changed form CLI mode to vManage mode and the system reset the login password to default.

The system mentioned that it can only be done through the device template, but I cannot log in.
I have tried the following solution below, but it seems vManage won't allow me to create a new user login

I tried to change the password for admin, but the system still reset to the default password.

May I know if there is any way to reset the password, or do I need to rebuild it and how to avoid this issue next time?

Thanks

system': This device is being managed by the vManage. Any configuration
changes to this device will be overwritten by the vManage after the control
connection to the vManage comes back up.

and cant get into the GUI .
