Template_GetDetailsPageName not triggered after the first requirement

ALM 24.1p1  I have 2 Requirement Types that have different fieldsets. I have workflow to set up the fields. Each requirement type has a second tab configured with fields on it. I assign the tab name in Template_GetDetailsPageName (select case on req type).  When I log in and select one requirement Template_GetDetailsPageName is triggered and the tab is named correctly. However, when I move to the second requirement (of the other type), Template_GetDetailsPageName is not called at all.  It doesn't matter which one I select first after login, it works like this.
