Ok.  After trying all of the links and suggestions offered, I decided to contact Intuit Support.  I got a call within 5 minutes, got her linked into my screen and showed her my issue.  Then she went through all of the knowledge base on her end.  We were not able to determine why or how this happened.  The solution ended up renaming the HomeBase folder in BaseWin23.  Then after updating the software, we opened up the application which build a new HomeBase folder.  This resolved the missing EF Client records problem.  Cudos to Amanda in Intuit Support.
