Hi hitmusic100,
unfortunately the logs don't show anything wrong. Screen seems correctly mapped to the same screen indexes/IDs.
Could you please try to reset display preferences running the following commands in a Terminal:

sudo rm -f /Library/Preferences/com.apple.windowserver.plist
sudo rm -f /Library/Preferences/com.apple.windowserver.plist.*
sudo rm -f /Library/Preferences/com.displaylink.plist
sudo rm -f /Library/Preferences/com.displaylink.plist.*
sudo rm -f /Library/Preferences/.GlobalPreferences.plist
sudo rm -f /Library/Preferences/.GlobalPreferences.plist.*
sudo rm -f /private/var/db/.com.apple.iokit.graphics
sudo rm -f /private/var/db/.com.apple.iokit.graphics.*

sudo rm -f ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist
sudo rm -f ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist.*
sudo rm -f ~/Library/Preferences/.GlobalPreferences.plist
sudo rm -f ~/Library/Preferences/.GlobalPreferences.plist.*
sudo rm -rf ~/Library/Preferences/Caches

Some files may not exist on your system.

After removing the files, reboot the machine and then connect the DisplayLink screens again, setting the desired layout. Grab the ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist file.

Try to repro the issue (switching from the Lenovo laptop) and if the layout is not correct please grab again the ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist file. I'd like to check the difference in your display preferences before and after the issue.

Since your problem happens after switching from the Lenovo laptop , which driver version are you using on that machine? The problem could be triggered by the firmware upgrade (though it's not a known problem).
Thanks!
