husk turned into a zombie

I am 2Headphones the bug happened in my realm, I was lighting up the underside of my zoo and then I mined a block that was holding up a block of sand. A husk that was in that encloser drops from in the encloser into the water that is below my zoo, so I replace the block and grab my capture net catch the husk and then when I drop it back into my zoo with the capture net the husk is now a zombie? This is a very weird bug that should be fixed.
