Bug with "For Single Record" & "For Multiple Records"

Bug with "For Single Record" & "For Multiple Records"

Hi,
I removed "Duplicate" button from "For Single Record" under "Actions" in "Quick View" of a report. PFB the configuration.

However, the changes don't reflect in the UI. PFB

The changes would reflect only if I remove that button from "For Multiple Records" as well. 


And the same goes for adding the button as well. I have to add it in both places to get it displayed in the UI. 

Is it not possible to hide it in one place, "For Single Record?"
