Training assistant do not see all the historical data?

Open Kulg web page; Garmin is connected; historical data synced from Aprill till now (October) and exist in Activities.

Click Training Assistant icon on bottom right.

See the message: "Training assistant works best with 2+ weeks of training data. Suggestions stay general until your history builds up."

Expected result: Training Assistant is able to analyse all the activities from Activities folder (not only last 2 weeks)
