Remove Templates for Elements in PI System Explorer
Currently, when you remove a template from an Element in PI System Explorer, you'll remove all existing attributes from the Element.
There should be a functionality in PI System Explorer to remove the template without making changes to the attributes for the element.
Currently, the only workaround is to use PI Builder to remove the template without removing the Attributes associated with said Element.

PI System Explorer should ask if the attributes should be removed or converted to non template based attributes.
