Sketch – Menu as displayed not updating to Menu in dashboard

How can I reset my menu (page order display) to align with the Menu Structure on my dashboard? For example, the page slotted as the second item in the menu displays as the fifth (“Gallery”). Also one of the parent-child designations are displaying as separate items (“Bookshelf”), and not pulling from its assigned Category. The main menu display does not update whether I try to move, delete or add pages.
