Competitive Drive Level Lost?

So I've been going through competitive drives each time they come up for the last little while and I just noticed I seem to have lost a drive level entirely even though I haven't skipped a drive recently. I completed the Team Drive and got my level up to VI and I have a screenshot showing that my drive level is VI dated September 9th. I noticed a few days ago that my drive level dropped back to V and I thought that maybe I was just making a mistake and didn't realize I was always on V until I saw my screenshots.

So did Blizzard maybe make the Team Drive not count towards the drive level and only changed it after the fact? Or is something else going on here? Did anyone else notice they lost a drive level too?
