CRXKnives: Knockback & Basic Skills | ZP Problem

[ghostcapgaming]

Hello, I have problem with CRXKnives knockback and basic skills plugin.

The problem is:
After i get infected by zombie, or using t virus. I still have the speed and knockback from the knife that I choose from the menu.
For example:
Nata knife
- Speed 500
- Knockback 1000 700

After I get infected, my speed still the same and the knockback was still there. I want to fix this, but i don't know how.
Please help me!
