Question about prefix/suffix tiers

I would like to know if this is a bug or a feature.

After sucessfully using combinator, I used exalts to fill up the prefixes/suffixes slots of the item. I ended up having one T13 life prefix that gives me +12 life, and a T8 stun treshold that gives me + 30.

On my current armor, I have a T4 stun treshold suffix that gives me + 128.

Isn't higher tier supposed to give higher values? What is it with that poor life prefix that is supposed to be high tier?

So if this is a feature and not a bug, could anyone explain a bit the deeper mechanics so I can understand what went wrong because it currently makes no sense to me. ^^'

(I have taken screenshots of both items but don't have an online space to upload them, I can send them somewhere if wanted/needed.)

Thanks in advance for your answers!


Edit: This is on PoE2, was done yesterday, and here are the screenshots (thx for the tip)

Which game?

Approximately how long ago was that life roll originally created?

I'd typically recommend Imgur as a solid free option.
