Problem on modifying keyboard shortcuts

I modified my “copy as” shortcuts in the settings as shown below.

It worked when I tried my new shortcuts, but the context menu did not reflect my modifications and remained set to the default.

Thus, the new shortcuts work, but the UI does not reflect the corresponding changes.

One more thing about the last item, “Location URL”, does it refer to the “copy as URL” or “copy as resource link” shortcut? In my testing, it seems to correspond to “copy as URL”. Could anyone clarify this? And why does it not show the shortcut in the context menu?
