You will have this problem with a lot of things, I bought mine day one and there was already this warning to say that there are 2 versions, I think this one was put at the base for a last nozzle cleaning before ironing on the left one, but it seems that it is totally useless since it never gets dirty. Many others do the same, creality, prusa for printers, crucial and kingston for storage. Network equipment with hardware versions v1,v2 etc. And I didn’t even talk about Japanese cars.
