Detail

If you have a form that submits to the save script, and the form has multi-value parameters such as checkboxes or multi-select, only the first value is passed in case there is a redirect to the login screen, e.g. unauthenticated user.

Cause: The login form has hidden values that pass along all URL parameters. This is done with the help of QUERYPARAMS variable. That variable only took the first value.
