Missing some Windows client pre- and post-script output at server GUI Log view

I’m using all scripts at client site

prefilebackup.bat
only the output of this script is at GUI Log available
example of the beginning of a incremental file backup, at the end no output of the post script

postfilebackup.bat, preimagebackup.bat, postimagebackup.bat
all output of these scripts are not shown at GUI Logs
example of GUI Log for incremental image backup

It would be nice to have this also visible at Server GUI Logs
