PSS 777 wheels problem with FS2004 default panel

I am not an experienced pilot so I usually try to use a FS2004 default panel.When I changed the PSS 777 panel for a default FS2004 panel the PSS 777 wheels are altered to a position where they look like during take-off but reversed.No other aircraft type has this problem.I have enclosed a photo to show the effect.Can anyone explain what has happened and if there is a solution.Maybe a "line" change in the aircraft file?Also is there a way of putting a default panel in the PMDG 747 so that I can use a normal flight plan and not,for me, the complicated FMC.I am still learning.Christiaan
