Detail disclosure button not showing in checklist tutorial

Hi all, Xcode 7.3.1, in my Checklist tutorial, page 111, “Go to the table view cell in the storyboard and in the Attributes inspector set its Accessory to Detail Disclosure” Should change that checkbox to an “i” with the circle…for some reason when i Run the build and test, it still shows it as a Checkbox. Has anyone seen this before?

It does show however in Main.storyboard, but only does not when running in the simulator. Also, interesting enough, the checkbox to the left doesn’t clear when selecting the row. hmm i seem to have missed something at the start of this step. it worked prior.
much thanks

Did you try erasing the app from the simulator and resintalling/rerunning?
