Severity: 4-Minor


In TMSH, 'none' is a special keyword for attributes of type string that is interpreted as an empty value. However, in the APM user interface, if you type 'none' for any field expecting a string value, it is not considered empty.


The configuration does not operate as expected.


Occurs when typing 'none' as a string value throughout the APM GUI.


Leave fields blank if you want them to be empty in the APM GUI. Do not use 'none' to mean 'empty' for any field requiring a string in the APM GUI.
