Signature Weapon Does Not Grant AB

[The Rambling Midget]

Description of Bug Experienced:
My Rogue with Signature Weapon does not receive a bonus to AB when using the chosen weapon. +1 DMG and +2 Intimidate are being applied.

Steps to reproduce the Bug:
Take Signature Weapon feat, then choose and equip a weapon.

Expected Result:
21 BAB + 14 Stat + 1 WF + 2 EWF + 2 Rogue Specialty Weapon + 4 Weapon + 1 Signature Weapon = +45 AB

Actual Result:
+44 AB (in Combat Log and on Character Sheet)

Update:

I notice that my +4 AB Signature Weapon has both +5 AB and +6 AB properties on it. My guess would be that Signature Weapon and Rogue Specialty Weapon are being applied separately, instead of stacking. Hopefully this is not intentional, as it would make Signature Weapon a near completely worthless feat for Rogues.

I've experienced the same issue on PGCC. The AB is clearly not applying.

Edit: re-equipping it made it work, i think

You do often have to re-equip certain items in order to activate Arelith's custom bonuses.

I tried it on my Rogue, and the problem remains. It should, however, work for any character that doesn't have a weapon AB increase ability.
