Polar Autosync

To update my training history I reconnected Polar History Importer and imported all missing runs on Monday morning.
The Polar Auto-Sync still offers Connect option, however, I hit this button again.
Surprisingly, the evening training automatically appeared in Smashrun. Does it seem work although the web app doesn’t say: “it is connected”? What would happen if I disconnected Polar History Importer?
The Additional Run Info strangely shows “Source; SUUNTO”. I have no connected Suunto device or service. The training happened on 4th Nov 2019.
My next runs are scheduled for the weekend, I will check what I will get.
Cheers!
