Possible double zombie spawner

Hello!

So I was just messing around on chunk seed and I found this seed with a double zombie dungeon two blocks from each other. However, upon loading the seed, the said dungeon doesn’t appear at all.

The seed is -5452156810671671375 on bedrock at the coordinates -2304, 61, -1051 and -2302, 61, -1051 and appears on the maps from Bedrock 1.21.120 – 1.21.132 and Bedrock 1.26 on both an older and preview version of the website to which I’ve loaded up on both versions with no luck.

I’m not sure if I’m being a bit too persistent with finding this, but I would like to wonder if this possible double spawner actually does load in some way or if it’s just a genuine accuracy error, which is most likely considering that I’ve loaded this on two different versions.
