question about runepages for riot staff

So in my collection right now, for some reason, I have 2 quintessences that kind of contradict each other, mind you one isnt flat and the other scaling their both flat,

but for some reason, I have a single greater quintessence of attack damage for 1.25 and the other full set I have is 2.25, whats going on here? I checked the shop and apparently this 1.25 version doesn't exist and it's kind of odd to me, any insight riot?

if this is indeed a glitch, is there any way I could get this extra quint traded for another?
