Mirror Sync didn't delete a folder with contents on Mac Catalina

[WorksPrettyWell]

Hi there FreeFileSync folk.

I’ve used your app for a year or so now and have been pleased with it.
Yesterday, I downloaded and installed the latest version 11.1 for Mac Catalina and ran it to Mirror Sync files from my usual collection of folders in my environment to the OneDrive folder, still on my desktop. The OneDrive cloud was not connected.
I had a folder (any quotes are not really part of folder or file names),
/Users/Mike/Philippines/"Building and Occupancy permits"
which I’d split into two by (I assume) creating a new folder,
/Users/Mike/Philippines/"Occupancy permit"
and renaming the original folder to,
/Users/Mike/Philippines/"Building permit"
Each folder has a few files in it.
After the sync ran, without any errors or warnings, I noticed that the folder which had been previously synched over was still present although it should have been deleted, namely,
/Users/Mike/OneDrive/Philippines/"Building and Occupancy permits"
This folder has no out-of-the ordinary permissions on it and no ACLs:
drwxr-xr-x 5 Mike staff 160 17 Aug 22:20 Building and…
You’ll notice as well from the date on it that it was updated or created with a previous sync and was not deleted as it should have been with a previous version of FreeFileSync – it had just gone unnoticed by myself.

My excuses if this bug is already well documented but a quick search for it didn’t reveal it.
I include pics of my Filter and Synchronisation settings.
Cheers,
Mike

Sorry if I break Forum rules but I can't figure out otherwise, how to add something extra to my bug report of earlier (as I couldn't report a bug under any other subject apart from "Localization".)
Anyway, just used FFS on my Windows 10 machine to Mirror sync from the laptop's OneDrive folder to my normal user environment.
In my user environment, a folder was once named "Unlawful Detainer case for eviction, RTC".
I had renamed it on my Mac to "Unlawful Detainer case for eviction, MTC".
Subsequently, it became renamed also on the OneDrive folder on my Mac, then in the cloud and then on the OneDrive folder on my Windows laptop.
From here, I tried Mirror synching to my normal user environment where files and folders seemed to get nicely mirrored. However, the previously named folder "Unlawful Detainer case for eviction, RTC" was still there although it's contents had been removed! As on the Mac, I had the "Permanently Delete" option in the filter selected. Hope this can be fixed :-)

Can you clean up your paths in the first section? You have back slashes and forward ones, not really sure what everything it supposed to point to.

In BSD Unix, the back-slashes are an "escape character" indicating that a "special character" is about to follow, such as a space or apostrophe... I'm not so sure if the same applies in the Windows (or is it still DOS) operating system.
