Thanks for the feedback.
Yes, “Admin menu access” add-on would be a reason of a problem. It blocks access to all URL with main part from admin menu if they differ by arguments list. If URE sees blocked URL it redirects user to the 1st available URL.
If you use “block not selected” model in “Admin menu” you can invert your selection for menu items and use “Block Selected” model as a workaround.
