Using any battery with the word "fire" in the name is not a good idea. They are low rate on the scale of safety and quality. You can use it at your own risk - but I personally would not. I would rather avoid a battery venting incident so close to my face. Not saying that that would definitely happen in a few days use. You may use it and have no issue at all. Its kind of an "is the risk worth taking" to you personally thing. I would advise against it

Better safe than sorry!
If it is 2 stacked 18350s - please dont even question using them! Avoid stacking batteries whenever possible. There are certain rules one must follow if they have a mod that requires stacking or they stack to up voltage in a mech mod. Stacked batteries are married once they were stacked - battery A and B are now a pair forever. They need to be equivalent in age and # of charge cycles. Otherwise - the stronger battery can rob the weaker...amongst other issues.
Look up Baditude and read his blogs - he has compiled tons of amazing info into a few well written, concise, easy to understand blogs. He is the Guru of everything battery!
I hope this helps and if you are able - I would take all of the batteries back to the B&M and get your money back! Shame on them ICRs and trustfires. Not surprising - but SHEESH.
