Renault Mk field is displayed differently since the update. Previously it was a simple hard '1' that would display in thumbnail view as well, now it's the standard 'Série 1' as displayed with other French cars.

I noticed this when I added this Mégane: https://www.imcdb.org/vehicle_1856500-Renault-M%C3%A9gane-X64-2000.html

The ones listed as Megane (w/o accent) have kept the old Mk display, such as this one: https://www.imcdb.org/vehicle_930204-Renault-Megane-X64-1995.html
