What am I doing wrong here with this library extraction?

I just came back to the game for the first time since WoNY released and the first thing I'm trying to do is fill up this library.

I have been doing pretty well with the system so far understanding how to identify upgrades etc. But this is puzzling me.

You can see that these two rifles are rolled with the highest amount of Crit chance, and Headshot damage and I do not have either of these stats in my library. I have extraced exotics before, and they are both definitely rifles. No idea why I cannot extract these stats.

Any ideas?
