Configuration Backups Not Restoring in v10

My v8.4 configurations were saved to spare me the time-consuming re-creation of piles of firewall rules. Today I installed a new version of Win10 and before installing v8.4 I checked for a new version of CIS. Version 10 appeared - nice! Except imports result in nothing added. Incompatible, or what?

There are some posts indicating your issue and it’s probably true. On the other hand, version 10 was not served as internal update.
