Zombies in peaceful mode
I'm experiencing zombies in one of my survival worlds in peaceful mode. I have a screenshot to show that it's in peaceful, and you can see the zombie in the background.
I know it's not a graphical glitch, because I checked it was in peaceful, returned, still saw it present, and successfully attacked it with a sword. I got the screenshot after that.
I've only confirmed this bug on the latest stable release of the Java version. I don't know if it's present in the beta, so I'm not sure if it affects the drowned.
Environment
Windows 10 64Bit. Java version 1.8.0_102

I'm not sure what conditions created the problem, so I don't know how to reproduce it. But if I encounter the issue in the wild again, I'll do that.
In case this issue also exists in the Bedrock edition, what are the equivalent steps for Windows 10 Edition?
@Nate Watson It's very possible that you are clicking on peaceful in the menu without getting out of the menu. The changes aren't applied until you exit the menu.
