Eta pistons ? quick qeustion

[e30m20TurbO7]

so i orderd some new piston rings , and the old rings were cast iron , and the oil ring had little slots ,
did they change the design of the rings?here are the pistures of the new rings
, also i ordered rings for a 1987 325e 2.7 but for some reason it says on the box of the rings that its for a 1.6/1.8/2.5 the oil ring is the only one that doesnt look right to me
11 25 1 713 192
