It's been officially stated that the reason they don't recognize each other is because of the difference in personality compared to their civilian forms and the change in their voices (which is more obvious in the french dub). Marinette is used to Adrien's calm and soft tone of voice while Cat noir's is more flirty and high-pitched, Adrien is used to a confident and strong-willed Ladybug while Marinette tends to act silly and clumsy in front of him.
