More than likely means they haven't sold enough tickets in the section you bought, so have moved you to those seats to block out the section to make it look fuller. Happened to me when they had the Revolution Rumble, got to the door to show tickets and had been moved to 2nd row as they didn't have a row where I had originally bought tickets(4th). So think you will be better off and have no issues. Same happened to me for All In, had seats which were now used for the giant canopy, got bumped to just behind ringside mega expensive block so I'm happy they did.
