I had this problem in the Switch version as wel. I saw one post that about this that was marked fixed while it clearly isn't. Raids can spawn underground which is a pain when it happens and is not supposed to occur. Also when I did one recently It said there was only one raider left while there were clearly multiple pillagers still in the cave.
