Unable to delete View from Record

Hi Folks,

I'm editing the list of views on a Record. I was successfully able to delete two of the views and save the changes. When I try to delete a third view I get the error.

Steps I'm following:

1. Open Record in Designer
2. Click Views
3. Click Red X on View to be deleted
4. System removes View
5. Click Save Changes
6. System displays Exception

HTTP Code: 500

APNX-1-4198-000

Any help appreciated
