I have all the required requirements for ferocious but won't activate the skill

This is a known issue. The problem is that the talent won't unlock when you exactly match any requirement value. In your case, you're trying to unlock Ferocious with 3832 Electronics. Increase your Electronics stat to 3833 or more and the talent will unlock for you. Hopefully this will be one of the many many things fixed by patch 1.6 when it arrives.
