Automatically using Legendary Cores without notice

[Tobahas]

So after getting the new Companion mods. I've levelled them and in the process it's automatically used the only 2 Ledgendary Cores I had. 

During the fusing of the mod it does say press 'X' to use them (which I Didnt press). But they have been used automatically without any message or warning its about to be consumed. It just shows up as credits and endo are being consumed

 

Please fix it. Thank you
