Vanishing Effects Settings

I have an annoying challenge that has been going on for more than a year.  Randomly vanishing effects settings.  I first noticed it a long time ago with Altiverb as sometimes when I open a project back up it has gone back to it's default plug-in settings.  I took it up with their support but have since figured out it's not just Altiverb.  Waves Maximizer, The Glue, etc.  There's no detectable pattern to it except that it happens, Sonar upgrade after upgrade, project file after project file.  Any ideas?  Running Win10, and currently running Sonar 23.4 build 38.
