More Info: Here is a link to the Mahle catalog:
MAHLE Aftermarket North America | Piston Ring Catalogs
You can find the detailed ring set description on page 328. It lists the individual ring profiles, and you can refer back to the early pages in the catalog to see the profiles. I cannot find the top ring profile that matches either that you show (RF-10YF); one of your rings does look close to the ring profile shown for the 2nd ring (BT-10).
I'd surely go back to the shop and at this point. Actually, for me, I would be thinking of getting the $$ back if I could, and even if I couldn't, just get a known ring set.
