WORKAROUND:
Attached is the hot-fix. Note, this fix only work with version 6.X only
STATUS:
Issue is fixed in Toad Data Modeler 6.2
HOT-FIX:
If you want to use the option then use the system package which they could use to overwrite the current one.
You should place the package into INSTALLDIR\packages\System, where INSTALLDIR is the TDM installation folder, by default C:\Program Files\Dell\Toad Data Modeler 6.1\. You will have a package by the same name in there.'
If you replace that and uninstall then will have to remove it manually because it would have been added manually.
C:\Program Files\Dell\Toad for Oracle 2016 R2 Suite\Toad Data Modeler 6.1\Packages\System
