Unable to equip certain daggers

So I found this out while playing the Hayato Class (Samurai) which in ChaosMS is the bandit class. I can't equip any daggers over level 40.

One's I tried to equip:
Level 55 - Bushido Req Str 30
Level 60 - Serpent's Coil Req str 50, Dex 100
Level 70 - Golden river Req str 55 Dex 110
Level 80 - Dragon's Tail Req Dex 120 Luk 210

even after I would take off all my EQ's that boost my stats, I still can't equip those daggers.

Same for me, having very bad difficulties trying to freaking equip simple daggers.

I'm a Dual Blade and I couldn't even level cause you can't equip certain daggers or any kataras. Eh, it's only Day 1.

You have to have like 10 more of the Req stat to equip. Its being weird.

It's caused by physical training. The Dex you get from it isn't being calculated thus you're not having enough stats.
