There is an audience of users that (based on recommendations from OSIsoft staff) overrides analysis templates - creates an analytic in a derived template with the same name as an analytic in the base. They can change the input attributes or even the equations in the overriding analytic. This results in multiple analytics showing in derived templates. This seems to be an 'unpublished' feature. If an element is selected, multiple analytics of the same name may appear but only one is enabled to be selected/used.
The issue - if a user has selected the derived element template and wishes to do a preview of an overridden analytic, they must select an example element. In these cases, when they click on the select Example Element link, the list includes all elements using the base template, instead of just those using that particular derived element template. This is very misleading - especially when overridden analytics are in multiple levels of derived templates. See case 00760876.
