External imported workout do not give correct difficulty ... and thus prgression level

I bought a Trainingplan on TrainingPeaks and imported it in Trainerroad.

All the imported workouts are “achievable” and get a low unrealistic progression level on the targetted zone. Is this normal behavior because of externally imported workouts or is this a bug?

I noticed when I hoover over the workout graph that the time interval mentionned on the hoover card does not always match the time on the graph.

Will the progression level, TSS, IF etc … “actualise” at the moment of finishing the workout and thus recording the real time intervals? I am not sure how this works? Thanks.
