From your own code, values are different in several places

frameSweet = register(new ItemFrame(120, 1.1f, 2.5f, 1.0f, 0.5f, "frameSweet"));
frameCooled = register(new ItemFrame(300, 2.0f, 3.5f, 0.8f, 0.25f, "frameCooled"));
frameMutating = register(new ItemFrame(240, 1.5f, 0.9f, 1.0f, 3.0f, "frameMutating"));

The Mutating frame is what caught my attention.

Woops thats a typo on the wiki
