Amalgam furax body count not working

[Nebu4]

Hi, I recently tried this mod (amalgam furax body count) out and it seems like the knockdown at melee kills doesn't work. Killing enemies proccs blast (only removes accuracy) on enemies but that's really it, it doesn't knock them down.

Also, is it normal that some specialized launchers like the penta are not affected by that mod even though it says that it increases the blast radius?

Thanks for checking this out!
