Monk axe dual-wield doesn't work

On my Spellbook, in the General tab, there’s the [Weapon Skills] skill whose tooltip says that I have Dual-wield for Axes (among others in the list). But when I try to equip two One-handed Axes, I’ve get the following error message: “You cannot dual-wield”. The weapon I’m trying to dual-wield is [Sentinel’s Tomahawk] (from Nathanos event).

So… can I dual-wield axes or can I not? Is the [Weapon Skills] tooltip wrong? Is it a bug?

Thanks!

Silly silly question, but are they both not unqiue, main-hand, or off-hand classified weapons? If both are any of these shared, that may be why…

One Unique will have no impact, unless the other is the same item. The “main-hand” classification means it may only be in your left weapon slot and “off-hand” meaning only to be equipped in the right, no exceptions to this. The only dual-wielded item classification that may go in either hand is “One-Hand”

Hope this could be of some help, in some way.
