Fines disappeared???

In December I got two huge speeding fines from Ras Al Khaimah, with 6 black points from each (12 points total). They were non-payable, so I was planning to go to a police station to deal with them.

Then in early January I checked the fines again, and instead of non-payable fines, they turned into payable black points (same total amount). And today I checked again, and all fines and black points are completely gone!

Could it be that they discovered that the camera wasn't calibrated and cancelled all fines issued by it? Is it something else? I mean, I'm not complaining, but it's so weird that this happened.

Side note: I never got flashed on the road, but I believe that the fines came from a temporary speed camera placed on Al Shuhada road (which has no business having an 80km/h speed limit, but whatever), which got installed very recently and doesn't have a camera flash.
