🐛 Bug Report: NULL and FALSE values on boolean attributes show the same when selected

### 👟 Reproduction steps

Just create a collection with a boolean attribute, and then create a document and set the boolean to false

### 👍 Expected behavior

The expected thing that it should do when you click false, is that "False" should be written when selected

### 👎 Actual Behavior

When you select false, it will appear as the value has not even been set to anything (Same thing as when it's null)

Value selected to null

Value selected to False
