Where did my custom topics go when I change the page set grid size? (Core First page set)

The Core First page set provides 75 + pre-populated topics and 6 blank custom topics where you can add your own content. The custom topics are accessible at the 1x1 grids size, all the way through the 8x10 grids size, so no matter where you start out, those topics will transition with you as you grow the grid size. However, where you access those custom topics  from depends on the grid size you are using. If you are using the emergent grids, 1x1 through 2x3, the custom topics are linked from the Supported Navigation page. If you are using any of the bigger grid sizes, the custom topics are access from the Topics Menu page. Both pages link to the same custom topics pages, but customization to the linking buttons, label and symbol, don’t transition from the Supported Navigation page to the Topic Menu page. If you transition from an emergent grid to a bigger grid or vice versa, your linking buttons will need to be updated, but you will NOT lose the content you added to the custom topics pages.
In the example below, if you started on the 2x3 emergent grid and create the custom My Class Friends topic, then transitioned to the 4x4 grid, your custom topic would still be accessible via the Your Topic 1 button. In this situation you simply need to update the Your Topic 1 button with the proper label and symbol. The same would be true for the other five custom topic buttons.
