Strange thing

I flew my first flight from LFPG Charles De Gaulle Airport and had an unusual event take place. It was night time and I had pushed back and turned on the progressive taxi but for some strange reason it kept disappearing I had to use spot mode and look at the plane from the front to the back in order to see the progressive taxi line. I have never had this problem anywhere else so it has to be something to do with the airport. This is a stock airport and nothing has been changed. I have not added any thing other than a few flight plans so I doubt if something changed it without my knowledge. Now mind you this is not that big of a deal as I always copy down the taxi instructions and use FSMAP which brings up the map of the airport I am at and by zooming in I can see all of the taxi way letters and runway numbers so I am still able to get to where I need to go.
Just curios if any one else has had this problem at this airport and what might be causing it. Now the aircraft I am using is a PAYWARE A340-400 from Just Flight a package called AIRBUS LONG HAUL COLLECTION which has three different models of the airbus and a ton of different liveries.
Any ideas as to what might be causing this?
