Can't see history and contacts in Teams after successful migration from Skype

I transferred messages and contacts from Skype to Teams.

Initially, when transferring, I saw the result - contacts and messages appeared in Teams.

However, now I logged in again (after a long break) and I don't see anything - no history, no contacts.

The last time I logged in to Teams, I was asked to select a "default messaging profile" (as I remember it right). There were two slightly different entries. I chose an arbitrary one.

Probably, I made a mistake with the choice.

Previously, I had an old Skype account - by login, not by email.

Maybe this is the reason for such a split of profiles? How can I now select a different messaging profile now?
