I just released version 6.5.1 which fixes this issue.
You might wonder what happened. While I was trying to make the 3.5.0 release and after I went through all our release pre-flight checklist the Internet went down at the office (jut my luck!). I had to switch to my laptop and go to a different location with working Internet to make the release, after running an abbreviated version of the release pre-flight checklist. The laptop was missing links to three language files which caused this restoration issue. This is something we had not come across before. I released a new version to address it and I am adding a full restoration test even to our abbreviated pre-flight checklist to prevent a future occurrence of this issue.
