Thanks for providing your file. Sorry I was mistaken, I believe your issue is not related to issue #1190
which relates to Polar Pattern, this is not the case here.
This is a separate, third issue that does not depend on the datum plane: even if you select a face on the body, it fails to pad the second cylinder.
BTW is there a specific reason why the second set of circles is not constrained to the horizontal sketch axis, but is on a line only angled 0.0165833 degrees from the horizontal? This angle value is so negligible as to suggest some error...
