enchantment book text color and zombies going through doors

this could be a duplicate but i'll report it anyway, just to let everyone know. the enchantment books doesn't have color on the text, also goes to items that are enchanted. i was testing the zombies if it can break a door, now i heard only special types of zombies can break it and it can break doors in hard mode, but i tried both of those and it didn't work, i summon a ton of zombies with armor, tools and baby zombies riding a chicken. instead they went through the door.
