Villager always changing to cleric with no brewing stands in Creative Bedrock

I made a town in creative in a jungle and I wanted to have villagers wandering around to make it more lively. I made a nice temple and I wanted to have just clerics in there but it was incredibly difficult to get three as non clerics kept spawning with a brewing stand placed in front them. I then decided to place villagers around the town and they were almost ALL clerics! I put them in a small hole with lecterns, composters, grindstones, anything to get regular villagers to spawn and they were the other villagers for like one to two seconds before changing back into clerics! I'm so confused! Some of the non-cleric villagers that did spawn were let out of the little hole and walked around before turning back into clerics. The only brewing stands are in the temple so I have no idea why they're changing.
