Different Technic Engine Cylinder parts in set 8041?

Hello all, first time poster.

I was just building my 8041-1: Race Truck whenj I noticed I had two different versions of the Technic Engine Cylinder part (part number 2850). This stuck me as very odd and set off alarm bells. My partner bought this set for me from Toys R Us here in South Australia. I have taken some photos comparing the correct part and the 'different' part. There are 8 of these included in the set, I had 3 correct ones and 5 'different' ones all up. All were packaged in sealed bag together, completely normally.

Can anyone explain the two different types of the same piece? One has the Copyright logo and LEGO on it and the other doesn't. The 'correct' piece has more of a matte finish too and the pieces are physical different, the hole on the side are in two separate places on the two pieces. Are the 'incorrect' pieces Chinese made per chance?

Old/new molds, and the batch made during a transition to the new: nothing more sinister.

Good to know :-). The rims are different to the ones pictured in the instruction manual too. Seems to be a very odd set, especially for a "Limited Edition" one.

Parts all too often don't match the ones in the instruction manual. I guess they use the design of the first mold for the parts in instruction manuals and don't update the pictures (regularly).
