Hitting the X and saving does not remove the custom view. The view (unwanted) is still there as a sub view of Individual. The view is also added to the bottom of the list as an additional view when I try to edit the view. I have 5 unwanted views now cluttering my program. The 3 at the bottom of the list (not sub views) do not show up in the Add/Edit Custom View window. None of the views are useful to me.
I successfully removed the unwanted Homebase views by importing a custom view export. A workaround is to install ProSeries on another computer, such as a laptop, create a custom view export. Import that custom view to ProSeries on your current computer.
Note to all: create a custom view backup and/or export before messing around with custom views.
