I might have found the cause. I had finished the day by going back to all of my internal forms and checked to see if all of the clients should have access, had access. All of them that more than one client assigned to the form, now had no clients, so I added them back in.
Then I closed up my project and went to sleep. I was thinking about a field that I forgot to add to the latest internal form. I logged in as admin, went to that form, added 1 field to the database and then the next step was to add that new field to the view. No clients were assigned. So there is something between adding a new field to an internal form that resets those multi-client views while leaving the single client view intact.
Does that help?
