6.6 Beta - Synchronise > Transfer Settings > Exclude Directories makes sound and is ignored

Using 6.6 Beta (build 17087) Windows 11.
If I select Synchronise, Transfer Settings, Exclude Directories I get a "bong" noise and nothing happens. Actually any menu selection off "Transfer Settings" does this as does selecting off the "OK" button menu in the synchronise popup.
The subsequent Synchronise operates on everything.

Recent post about 6.6.1 shows this has been addressed. WinSCP window was on non primary screen to the left of the primary. Moving it to the primary restored functionality! Thanks.

Yes, indeed, this has been fixed:
Issue 2423 – Some menus are not working on displays to the left or above the primary display
