Zombies with the "CanBreakDoors" NBT often do not make use of their ability, instead either just wandering around a house with a villager inside, or sometimes even just standing in front of the door without doing anything.
Command used to spawn Zombies:
/summon zombie ~ ~ ~ {CanBreakDoors:1}

Please check if your difficulty is set to hard.
Also note that not all zombies are able to break down doors.
Apologies, but I can confirm a modified version of this report: Zombies do seem to behave weirdly in villages even if they have the ability to break doors. The easiest way to reproduce this is to spawn a whole bunch of zombies with the specific tag in a village at night.
Yeah, in old versions zombies could break doors but in new versions (like 1.15) they can no longer break doors.
Hope they fix that because it kinda makes me disappointed
