Python3ForAndroid_r6.apk - application can't be moved from "system memory" to "internal memory"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Python3ForAndroid_r6.apk
2. Intall Python, extras and libraries
3. Enter Application Manager and try to move application to "Internal Memory"

What is the expected output? What do you see instead?
Application should be moved from "System Memory" to "Internal Memory", freeing 
the space. Unfortunately the "Move to internal memory" button is inactive.
This operation could be performed in the PythonForAndroid_r4.apk


What version of the product are you using? On what operating system?
I'm using LG-E400 with Android 2.3.6
