What are you missing?
A FIT exported from Garmin Connect and manually uploaded to Intervals, should have it all.
Don’t think this is related to the issue from this topic.
a picture is easier.
i am missing all my Cycling dynamics from my Garmin Rally pedals, and it is all into one segement.
The FIT file is ok, as I could get the datas using AI with Python.
The CSV looks to have also the datas… but they don’t show up.
I have deleted the activities, reimport the original FIT file from Garmin, with no success.
If this is not related, feel free to delete my posts from the topic, no worries

You have L/R balance in the summary, so the data is present and correctly identified
You mean the Intervals CSV exports?
If so, Intervals is receiving the data and you only have a display problem which can probably be solved quit easily by defining the correct Custom Streams and/or charting the correct plots.
You probably mean that the laps are not correct? If the lap events are in the FIT file, you just need to specify ‘Use Laps’ in the Actions menu.
If you used a workout from Garmin to guide the activity, then those lap events will not be in the FIT file received from the Garmin Connect API, but they will be in the manual export FIT from Garmin Connect.
It quickly becomes complex if you don’t know exactly what is going on.
I have compared the CSV, from my ride on sunday, and the one on monday, they have the same columns, so yes, the datas are there, but not displaying.
Point is, I did not change any settings in ICU.
And no workout used, they were “free” rides. But it worked also before with a workout planned or not.
And I tried the “use lap”, nothing.
Not all charts are displayed by default. You need to configure your display.
Did you add the charts for the different data?
There’s also a Custom activity chart displaying a summary of cycling dynamics
You can find it as a user created chart
Other examples are Power balance and torque histograms
Or a Custom stream with Rider position where you can see Standing/Seated, etc…
If you have electronic gearing:
