[digiKam-users] DK 7.1 and find duplicates

[digikam at 911networks.com]

DK 7.1.0 appimage on opensuse leap 15.2

I'm searching for duplicates to cleanup "my mess"

First I did the similarity range 100% to 100%: it worked
Now I'm doing 99% to 99% range. The problem is that DK finds images
that are not in the range:

1.00 to 0.94

Here's a screen capture: https://i.imgur.com/ejIiHUU.png

1. I do not understand how it works? Then what am I doing wrong?
2. Is this a bug? If it is has it been fixed 7.2.0rc?

Thank you
