BUG: Locking Weapon to Both Sets doesn't recognize attributes on weapon (explained below)

It seems that when I attempt to lock my weapon to both weapon sets, I am unable to do so. No right-click option appears. I am pretty sure this may have to do with the fact that, without the weapon, I do not meet its attribute requirements. Equipping the weapon thus requires me to first spec into the required attribute, however, once I have done so, the attributes granted by the weapon allow me to remove those temporary attributes.

The issue arises with assigning the weapon to the second slot. When trying to do so, the same issue seems to occur (or this is my best guess). No right-click option is present. Perhaps this is simply the bug in itself, but my best guess is that the already-acquired attributes are not being recognized when trying to assign it to the second (unequipped) weapon slot. Hope this makes sense.

UPDATE: Confirmed that this is indeed related to the attribute requirements, so not a bug, but definitely a bit of a QOL issue. Say, for example, one needs 5 more dex to equip their quarterstaff. You spec into that dex, equip the weapon, and then that quarterstaff gives you +30 Dex. If you remove that 5 dex you used to equip the weapon, you cannot assign it to the second slot. I really think this should be changed, just doesn't make sense.
