Thanks for replying.
I tried setting the global setting for Titles to "Show" and then Article setting to Global/Show or Hide, and none affected the Page as displayed on the Front End. The Global setting would persist regardless of the page/article setting. I also tried setting the Global to "Hide" and again, changing the Article setting had no effect.
I enabled the Cassiopeia template and the behavior persists.
Settings in "Articles: Edit" have no effect on the Global setting.
That's not what's supposed to happen, is it?
