Syncing bookmarks problem

How can I start a new sync line with the windows desktop version of brave.
I have an existing sync chain but I would like to start a complete new sync line.
Actually I have the options to “display the sync code” or to “add a new device”. Below I have the option to leave the chain, but when I try this nothing happens.
So the question is: How to discard the current sync settings and set up a new sync chain?

How can this issue be reproduced?

Expected result:

Brave Version( check About Brave):
1.15.75
