Great functionality with a confusing User Interface

Gemini has helped me more than once to identify duplicates and triples. Great functionality! But the user interface is a blend
of unusual and confusing.

When I try to remove a duplicate, I click the button “Remove Selected” in the upper right location. Nothing happens, because I have to do one more step to remove the duplicates with the “Remove" Button. Where do I find it? Not at an intuitive place. There are instructions to find it: “Use the button right in the lower corner to remove the listed duplicates.” At least it should say "“Use the button in the lower right corner to remove the listed duplicates.”

But why do I have to read these instructions anyway? Why not place the “Remove" button at the same location as the “Remove Selected” button? In this case no instructions would be needed at all.
