MIX RECALL PROBLEM w/UAD 2 Plugins

No one repleid to my previous post so reposting so if I don;t get any help, I guess I'll have to create a formal ticket with CW.   This issue prevents me from using Mix recall which is a great feature otherwise.   
 
 I discovered an issue (at least in my projects) that mix recall does not properly recall UAD plugins nor their settings between different saved versions.  If I store a mix and come back to it in MR, some UAD plugs are not properly saved or they are not saved with the settings.   This has caused me big issue.   For now, until I more full understand this or find a solution, I just went back to saving different versions of the file.   Anyone else experience this or know of a solution/workaround?
