Hi Michael,can you please send the screenshot of LEGS page on CDU ?

The real problem is, the CDU still is locked on a way point even after you've passed it, it doesn't lock onto the next way point.

Send me the screenshot of your CDU on the LEGS page and cockpit please.

Are you sure that you have clicked exec button to activate your route? Can you see altitudes and speed next to the waypoint?

Just a suggestion, Make sure you have your reserve fuel and cost index spaces filled out in the PERF page.
