if you bothered to read the link, that explains ALL aspects. not just the ones in the codex.
the aspect number in blue, is what it was when the item was dropped, or applied. the range is your CURRENT available range. Which changes constantly as you level up and get new gear.
It is extremely annoying for sure. I really wish they would change the system.
As far as your second example, the item that dropped with the stats was a higher “hidden” item level. Higher than what you have equipped. Again… its so annoying to try and keep track of this crap.
I also have 2 aspects I slapped on my gear that have a higher percentage than my current range.
