No... All the abilities you get you keep.. So for example if you have 20 pages worth of abilities. You can only use the abilities on the first 8 pages to upgrade the other 12 pages you still keep them.. As you use up abilities from the first 8 pages they will then be filled in with abilities from the remaining 12 pages
