Thanks for your message Mary Jane. I'm wondering if the Health permission need to be manually enabled on the iPad fro the sync to work there as well.

Please open Calistree on your iPad, go to the Profile settings page > Sync with Apple health, and click to Disable, and then Enable again.

Then please log a new session and let us know if that worked, thank you!

The only way I got around this is to open the app on the phone, continue (gtg) the session and immediately finish it, this way it gets logged in the health app
