flppos configuration

Hello,
I'm trying to config those flap settings via MCDU to ecam display.
I did follow those instructions and F5 comes with zeros as supposed.
When I push next detent (F7) zeros are still there and MCDU does not
recoqnize any movement. In FSX (throttle panel) flaps lever moves thought.
When I push next detent in MCDU it says flap 2 and ecam says 1+F,
I push F7 and nothing happens in MCDU FS flaps digits. I push again and then it
moves to flap 3. It seem that MCDU recognizes only three detents.
So my question is why MCDU does not see any movement after 0 and after 3
I wish to have 0-1-2-3-FULL (Because of my panel) , Thanks!

Do a forum search for "flap positions". There are a lot of tips from Thomas Richter on how to set up the CDU config file.
