beano | kv database | Database library

I know for a fact there is something pretty obvious here that I am completely missing, so your help is greatly appreciated.

I have a feature that provides two dropdowns. They contain the same data (the feature allows a trade between two people, the people is the data), but I want them each to get their own copy of said data.

Another part of this feature is that by picking Person A in the first dropdown, I want to disable Person A in the second dropdown, and vice versa, so I have the ng-options tag paying attention to a disabled property on the object.

The issue I have is that even with using a method such as Lodash's clone to properly create a "new" array upon first time assignment, every time I access Person A in ONE array (and specifically do NOT access the other array) invariably I am seeing that when I touch Person A, that object is updated in BOTH arrays, which has me flustered.

This feels like a down-to-the-metal, barebones Javascript issue (standard PEBCAK, I feel like I'm clearly misunderstanding or straight up missing something fundamental), maybe with a bit of AngularJS rendering-related fun-ness involved, but... What gives?

In my code there is a Bean Admin. One of the operations of Admin is creating Tasks and starting them.

Operation performed by Task is fairly complex. So it is split into to a few different Step classes.

This is kind of how my code looks
