Three persistent bugs

Hello I would like to report some bugs that I found in Minecraft Windows Edition in the current versions in Survival mode, come on! One is the villagers who do not reach adulthood, villagers are children forever. Second, in creating the 'cake' the buckets with the milk disappear instead of returning empty (In Pocket edition the buckets return empty normally). Third, the mules do not accept that they put saddles into uselessness. Well, I guess for now I just apologize for my Brazilian English. Thank you and see you next time.
