Wrong version number for Windows 10 Edition

What I expected to happen was...:
It would be version 1.2.0.2 for the app itself.
 
What actually happened was...:
It was version 1.2.2.0
 
Steps to Reproduce:
Note: Only Windows 10
1. Open the Windows Store.
2. Press your Profile picture and under that press "Downloads and Updates".
3. Notice that the version number is 1.2.2.0, instead of 1.2.0.2.
