The default for the favorites page is the page 1 default modes. There is no way to “clear" the favorites page completely as there has to be a mode in each of the 10 slots, and there can't be a empty/dark slot - that would basically mean the light is off ;)
Depending on what your goal is, you can customize your favorites page. For instance, if you want all the modes in favorites to be the same, you can save that specific mode 10 times. If you prefer to only have 5 modes in your favorites page, you can save each mode 2 times in a row (AABBCCDDEE), or your favorite 5 modes twice (ABCDEABCDE), so you have your 5 modes in the 10 slots.
Here is a quick video where Sean demonstrates how to save and organize your favorites that should help: organizing your favorites. Please note, this video is for flowlight-FS but the user interface is the same for the capsule 2.0.
