When I create a new document, InDesign CC 2014 automatically chooses one of my custom presets instead of [Default] (see below). Then I need to manually select [Default] to get a regular letter-sized page. Does anyone know why it would do this, or if there's a way to force it to use [Default] first? It's a small problem, but it's starting to get annoying.
When no document is open go to File > Document set up…
Make your changes there, all what you set up here without an open document will be the standard for any new document.
If you have several presets, go to the presets dialog and select the prefered setting and leave the dialog.
