Service numbers
What does the number (after the letter) mean, for the service intervals?

I had my "Service A5" coming due in a few hundred miles, so I changed the oil/filter, and re-set the system. Now it says "Service B7" is due in 10,000 miles.
Does that seem correct? What happened to the number 6? Did I screw-up the re-set procedure?

FYI: Bought my 2014 ML350 (gas) in May '17 w/ 26,000 miles. Now at around 36,000 miles, "Service A5" was coming due.
