Why does not Kodi write current state in log file?

Hello,
I use Windows 10 and Kodi v16.1.
I have a problem with log file.
The log file is not changed. Sometimes I want to look at an error of the addons log file.
But log file is not changed. It always stays the same.
I use Log Viewer for Kodi, the log file is also same.
Kodi does not write current state in log file.
My log file always looks like this is not changed. https://paste.ubuntu.com/23521860/

What kind of adjustment do I have to make?
