APU always consumes fuel from left fuel tanks

[MarcusVT]

I stayed at the ground for a long time with APU on so I got some inbalance in inner tanks. I decided to feed APU using right fuel tanks but it just got fuel from the left. Did I do something, is it a bug or an airplane "feature".
I grabbed two screens with only APU on and you can see that, despite the feed configuration, only the inner left fuel tank has fuel consumed.

The APU has its own fuel pump which draws fuel from the left inner tank. Starts automatically as you set the APU s/w to on. (The APU pump does not appear on the fuel page). So no matter the position of the engine fuel pumps the APU will feed from the left inner.  

I you want to feed the APU from the right side tanks you must set the LH side isolation valves to OFF and open the crossfeed vlv

Just for curiosity I decided to draw fuel only from inner right tank, so I closed the outer valve. The green light showing INNER fuel line is not being drawn, despite the fact the system are working properly. Just a cosmetic bug. 
BTW I draw the partial green line.
