Hey there! Welcome to the TR Community! 
I just pulled up your account to take a look, but it seems like the rides aren’t there anymore. Any chance you deleted them from your TR account?
If that’s the case, it could be worth just re-syncing TR and Strava. We have a good TR Support article on that in case you need the steps!
Feel free to let me or TR Support know if you have any other questions getting started!
