Elf Bar tastes weird

Hey guys, yesterday i bought an energy ice flavoured elf bar disposable and it tastes odd, and straight out of the box it tastes weird, it doesnt taste burnt it kind of tastes mouldy? Ive had the same flavour numerous times before and me + my friends agree that it tastes different and think its mouldy.

Is there anything i can do to fix this or does anyone know what caused this?

Thanks
