AE - Component release different in AWA bundle?

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

We have downloaded and installed AWA release 12.1.2. In AWI, we found the Version: Automic Web Interface 12.1.1.GA02-dev-feature-12.1.1-GA02-68435
Did we do something wrong or is it still AWI 12.1.1 that is delivered with AWA 12.1.2 ? 

Environment

Release:
Component: AAUTEN

Resolution

It's completely normal, for example, in the same AWA bundle release, the AE release is 12.1.2 and the AWI GUI can be 12.1.1.
The version of each component will not be exactly the same but slightly different.
