Speed of PFD and ND

Gentlemen ,I am building a home cockpit based on PMDG 737 and had to create a new window with FSpanel in order to have in copilot panel the PFD and ND.All is working nice except that the speed strip in PFD of the main panel is moving quicker than the strip of the copilot panel.What I have to do in order I get both moving at same speed?Also , when I try to install the 737-800/900 I get an warning saying that I must have a 737-600/700 installed , but I have the 737-600/700 installed.thanks and regardsAlberto Kunzel
