Blackwidow chroma v2 custom media keys not working!

Hello all,



I am encountering a strange issue.

I am setting the M buttons (M1 -> M5 found on the left side of the keyboard) as my dedicated media buttons ( volume up/down and mute) and the volume up/down are not working.Oddly enough, the mute button works, but I get no visual indication.



The keys used to work before, they just stopped now.

Synapse drivers are up to date, no macros set, and only one profile available.Also I have deleted the profile and started over and no result.



Any ideas?



Thank you!
