Drowned are brighter when holding fishing rod and nautilus shell

I was just about to turn it into day when I noticed 2 Drowned spawned with a Fishing Rod and Nautilus Shell. I thought it was strange that there texture was so bright then I noticed one without an item and it was normal looking. I decided to spawn a few in and noticed all the Drowned with Items are super bright and the ones without an item are normal looking. So one of the textures is messed up.
