Archived folders were missing (Program and Engagement stream) ?

Hi All,

Yesterday, I was archiving our last year programs. But i have noticed now that one Nurture folders (it contains 3 Engagement stream and 5 Default program) were missing in Marketing Activities that i have archived yesterday.

1. I have checked in all the folders, but not able to find it. Then,

2. I have tried to create a another program with same name, error occurred , that program name is already existing. Then,

3. I have created a program with dummy name and try to sync Salesforce campaign, It says that the campaign is already sync with another program.

Which means Program is existing but not visible. Could you please help me?

Thanks,

Selven R
