You didn't charge beyond 100%. Nissan doesn't let you access part of the battery at the top and bottom. 100% on the dash display isn't actually 100%. It's a bit less.
From your previous posts, it sounds like you have a '13, like me.

Agreed with what WetEV said. Also, if you are usually not charging to full, that might help exacerbate inaccuracy.

Normal. This happens even if you don't charge to 100%. The on-board charger heats up and so does the inlet. Next time, charge for at least an hour and open the hood while charging. You'll feel the entire PDM stack is warm.

As for the bolded part, when the battery is closer to full (usually somewhere past 92% (I don't recall the exact numbers) on the dash display), the car will begin ramping down charge power and then do 3 bounces at the end. Not much energy makes it into the battery during that phase. It's not linear or steady state near the top, unlike when you charge to 80% where it's basically the same power level the whole time (w/a bit of variance) then car abruptly cuts power draw to 0.

. Your previous posts mention you have Leaf Spy. You can see how many battery gids it goes up to. And, you can see the charging power. You'll see it go down just like my ChargePoint graph.
As I've posted many times, if the dash display is at 98% or so, often, when you unplug, it'll "jump" to 100%, even though a bit more juice can be added to the battery.viewtopic.php?p=423754#p423754viewtopic.php?p=339977#p339977viewtopic.php?p=446914#p446914

Not abnormal at all. If you charge to 100%, you'll have 0 available regen circles until you deplete the battery for a bit. At what SoC % on the dash you'll have all regen circles available varies, and can vary depending on battery temperature, condition and how full the battery was to start with. I suspect they just want to make sure there's no module that goes beyond some set critical high voltage and that's the limiting factor. For heavily degraded '11s and '12s, I hear there's very little regen.

You will NOT have a fire. '11 and '12 Leafs only could be charged to 80% via the timers. On model year US '14+ Leafs, they REMOVED the charge to 80% option. You have no choice but to charge to 100% or to terminate it early via either means (e.g. timer, unplugging early, EVSE with its own timer or that can be scheduled/remotely controlled). We have at least a dozen '14+ Leafs at my work who charge there. They go to full. I suspect many other pre-'14s are charged to full, as well.
