Time reported in “fitness” app is incorrect

Since the last update, 1.33.3, my Swift sessions are not entirely reported in “fitness” app.
In example today I use Swift during 1 hour but only 6 minutes are displayed in the “exercices” section of fitness app.

Which fitness app are you referring to?

the one connected with my Apple Watch.
… with the 3 rings.

I’m out then. I don’t use Apple products.
