When a field of type "ezboolean" has a value equal to false then the value is displayed as "empty" in Version Comparison - even though it's displayed as "false" in Admin UI content view.

Steps to reproduce:
1. Login as admin
2. Create a new Content Type "testct"

• Field1: Name (ezstring)
• FIeld2: Checkbox (ezboolean)
  3. Create a new Content item based on "testct" Content Type:
  Name: Test
  Checkbox: True
  4. Edit the created Content Item:
  Name: test
  Checkbox: false
  5. Enter the version comparison between these two versions

Expected:
False value is displayed

Actual:
"This field is empty" is displayed for false value
