Boss % not working

Hi so when I hit normal monsters I do this damage
Bstep on normal monsters

 Spoiler

Assassinate on normal monsters

Those are on the beetles on the east side of Leafre
Now comparing that to dojo boss monsters
Bstep on dojo

 Spoiler

Assassinate on dojo

 Spoiler

Now these are my stats on the stat window

 Spoiler

My %boss on dagger

 Spoiler

My %boss on shield

Can it really be because I have low %PDR? is that the main problem because I can get the leafre set and get %pdr nebs if I have to I just want to make sure that my weapon isn't glitched, so if you can help please do so. Thanks
