Is it expected behavior for "Blueprint Summary" Cell Links from an "Optional" template not to work?

Using Control Center, I am adding an "optional" sheet from the blueprint templates to some existing projects. While Control Center is then linking the identified "Blueprint Summary" fields from the newly added sheet to our metrics Rollup sheet….they don't actually function. Meaning they show a blue arrow as if they are linking, and when you double-click them from the rollup sheet they open up the correct cell on the newly-added template, but they DONT UPDATE at all. If data changes on the added sheet, the cell link refuses to display the new values. Is this expected behavior?? Why would Control Center even bother creating cell links that don't actually function/update?
