Are the 'Rider' medal quests broken?

I tried updating it again with a 90-day Croking mount; went up to 13/xx for the other two and Easy Rider is still stuck at 9/10. One of my alliance members obtained the medal recently and it worked for her.

I think it has something to do with how my Rider counts used to "reset" when I didn't add a mount into my collection after an extended period of time.

I got that medal back in the day, but sometimes the numbers get stuck... Weird if not all get stuck at the same time, though.
