This is a rare issue, but it can occasionally occur when building longer plans — especially if the new session cycles didn’t update correctly during the editing process.
To fix it:
Check that each new session has a name — unnamed sessions won’t show up in progress.
If everything looks correct and the issue continues:
Click the Edit button on the plan.
Delete and re-enter the session name and session cycle for each new session.
Save the plan again.
This will refresh the data and should correctly update your athletes progress.
