Probably because you combined them into your explosive rune.

Hello!

Just like what BustCheeksDesu, you might have accidentally combined it with others. Each time you feed a rune to other runes, it always gives a prompt message about it you might have clicked Yes without reading it that the other rune will eat up your Quick. Try to remember if that's what happened, thank you.

The truth is that I got my rune I just redeemed it together when I published, check the one for injury and the one for ini. I just said accept even though he had the padlock he ate it ..

well I'm talking to the support they are investigating so we will see what happens because it hurts here ♥ ️>

Why is season ranking from last year?

They did not want to return me my rune had the lock / padlock was blocked. How am I going to sacrifice my rune of months ... I put my complaint seconds after I acquired it and it disappeared. after 30 seconds talk to the bugg support ... this is not fair ... this is not going to stay like this this is the war

If only you could read some of the juicy info that keeps getting removed. Below the surface this game is DARK.

Hmm.

The question here is, did you locked your Quick Rune right after you redeem it because from what I'm seeing in your screenshot, your Inferno Rune is locked and feeding that rune to your Quick Rune that has not locked will result to Inferno Rune eating your Quick. If that's the case then it is Player Error and the game will not give it back to you unless Game Error or Bug is the reason why you lost it.
