In file transfer, remote computer is the same than the local computer

Since some time, without having changed anything in the TeamViewer setup, in the panel of the File Transfer, the remote computer is the same than the local computer, with just a (1) added in the name. I've tried to review all the settings, without success.

Take into account I've used this functionality for months without registering any issue.

Can you help me?

Regards
