I am using SwissA the Default size .
I noticed another thing ... some times in Landscape mode this doesn't happen and buttons appears in the right order , I think it has to be in an exact orientation to make it happen and fixing it is by just turning the mobile to force Portrait mode and go back to landscape (It works even if the Landscape orientation Lock is enabled )

It must have something to do with the Accelerometer sensor , it is now more confusing for me
