Statistics Menu shows impossible combinations for survival

The statistics menu show numbers in wrong columns for blocks and items that cannot be either crafted, or used in survival mode. Portals are shown as having been used 171 times. Coal is shown having been created 6,024 times (yes coal, not charcoal). Ink sacks are shown as having been created 321 times (not possible.) The only explanation I can think of is possibly using time spent on the creative inventory as legitimate ways to obtain this data?
