This is something that can happen if you upgrade from a B1UP prior to 126.96.36.199 and the upgrade happened while a previous version was still running and blocked the uninstaller to remove the datacheck files (something that has been fixed in the 188.8.131.52 uninstaller so it will not happen in the future)... Please do the following to fix your problem:
- Go to Administration > Add-ons > B1 Usability Package > Help > Troubleshooting and press the "Reset Datacheck" option
- Go to Administration > Add-ons > B1 Usability Package > Help > Troubleshooting and press the "Reset Xml" option
- Stop the add-on and start it again...
This will result in it creating its missing new database fields and ensure the any window is redrawn correctly.
