Completing Routes in workouts

Hi there,
Using a Tacx Flux S with my MacBook (software current). I’m doing the FTP Builder workout program and using different routes each workout. If the route distance is longer than the workout distance I just continue riding to complete the route or if the workout distance is longer than the route its pretty easy to see that I’m at the beginning of the route again and have X amount ks to go.
The last few rides, despite completing the distance (incl. lead in) the route does not show complete or a green tick. In this photo, I have completed my workout and gone over the k’s for Knickerbocker. I didn’t receive a tick for completing the route and I also don’t understand the blue bar. Can anyone shed some light for me? Thanks.
