For completeness I’ve quoted my existing answer below, but having gone through it all I’m satisfied that you have a new, updated tooth profile and all is ok. Thanks to David Richerby for linking to the R7000 cassette which has these circled features. I then was able to look at an Ultegra R8000 equipped bike yesterday and saw them also, not sure which cassette but it was new and shared these features.
Somehow your cassette has updated features, if it’s not a new R7000 cassette snuck into Rose’s inventory, perhaps selected new-design cogs have been included by Shimano and shipped out ‘early’.
No doubt in a few months these teeth profiles will be de rigeur and these questions won’t take (me) so much faff to answer ;)
The pair you’ve circled on the right are extra tall teeth that are a newer feature of Shimano cassettes that look normal.
The other three smaller red circles look to me like there is material missing from those teeth. That seems abnormal to me. I have looked on a 5800 cassette and include a stock photo below, I can’t see evidence of this missing material in either. Most teeth in the smallest two cogs are roughly symmetrical.
I would therefore follow up with Rose for advice if on the cassette you do have missing material (and it’s not just my interpretation of your photograph)
I’ve included an extract of the photo in Argenti’s helpful link, of both 12 and 11 tooth 5800 cogs below.
The profile of each of the teeth goes smoothly from the base of each trough to the full height of the tooth in a smooth curve, although the curve can be different on each side of various teeth, it is one smooth, continuous curve.
What I see in your photograph is that the three small red circles highlight teeth with a ‘step’ part way up the right side of a tooth, that then curves up to the top of the tooth. I think it’s abnormal for that profile to be across the full depth of the tooth
If this isn’t the case then I’m misreading the photograph.
