Gunslinger Perk Doesn't Increase Damage Deliverer and Silver Sidearm

[Nerikkaili]

Normally, gunslinger perk increase the damage of Deliverer and Silver Sidearm. But, when i install this patch, it no longer have any effect on those weapons. When i delete the mod, the problem solves. Can anyone help me about it?

 

Edit: I tried to re-install game. It's original. Next-gen.

 

Edit 2: I used the cheat system (deleted my old save)  and began a new. 10mm is effected the perk normally, but, Deliverer and Silver Sidearm still has problem. I took Problem Solver DLC gun with cheat codes to test and leveled up fastly to take Rifleman, and it's still working normally. The problem is with the Deliverer. If ı am not wrong, silver sidearm uses Deliverer model, so, ı guess that weapon affected as well.
