The wrong computers are displayed in the network!

Hallo!

My problem is that under Win 11 the wrong shared folders are suddenly displayed on the network.

Example:
Computer 1 with shared folders is also shown on Computer 1,
same with computer 2!

Until a few hours ago it was still really rum.

Releases were granted as well as the permissions.

Private network is enabled, as is the same workgroup.

I’m at a loss, does anyone have a solution?

Thanks in advance!
