The session Log getting disabled automatically

The session log in Winscp preferences is getting unchecked automatically. I reenable it back and again it gets unchecked. Due to this the exit codes are not getting displayed in most my scripts. Not sure what the issue is. Any suggestions?

In scripting, do not rely on GUI configuration. On the contrary, you should isolate the script from GUI configuration:

To enable logging in scripting, use /log command-line parameter:
