You want to fool me ???? What is wrong with it, that almost exclusively wages come instead of other monsters ???

Did you read the Guidelines as mentioned above? We need to be able to reproduce the issue, so we need the steps, including world seed, location, conditions, etc. It is likely that there are Blaze Spawners nearby in your fortress, which will produce a lot of Blazes. Also, mobs spawn in the nether based on the Biome, so it may be that you are in a biome where certain mobs don't spawn. Without additional information, and also something that shows that this only happens on a Realm (with the seed and coordinate), we can't determine if there is even a bug.

It is in the Nether Fortress where normally with spans. There are no Spwaners because 80% of them only blaze. Black skeletons are usually found in Red Fortresses. Since the update, mainly only wages (Blaze) have been received. All Blaze Spwaner was destroyed. Still, almost all of them are Blaze
