Unable to access "Resource Actions" or "Account Actions" dropdowns for ONE resource group

Unable to access "Resource Actions" or "Account Actions" dropdowns for ONE resource group

I'm running PMP 9.0 on Linux (upgraded from earlier versions).   Since the latest upgrade, I have one resource group where, even as a superadmin user, I cannot access the dropdowns for resource/account actions.   This functionality works for other groups of resources with the SAME ownership/sharing permissions.   Additionally, I noticed from the javascript debugger, that there are error messages when I try to open these dropdowns. See the screenshot below.

The image below was taken with the most recent version of Chrome, but I have had the same problem in various versions of Firefox and Internet Explorer as well, so I don't think it's specifically a browser issue.

I've been unable to successfully contact OpenManage Support so I'm hoping someone sees this here and has some ideas.   
thanks!
