Ground Finisher after knockdown

[Yperkeimenos]

Hi all, I've been getting some truly inconsistent results when trying to do ground finishers after knocking down an enemy. Sometimes the ground attack will be triggered along with its animation while other times i can punch the enemy to death,while being knocked down, and never get a single ground finisher. What i've noticed is that if i am too close to an enemy, when they are knocked down, i have to back away then come back over them for the attack to activate. I don't know if that's a bug or a game mechanic but i'm reporting it anyway since i couldn't find something on the subject online.

EDIT :  I've used the Prisma Obex for the tests.
