Camellia fencing grace/weapon finesse bugged?

[Tibbleton]

I've been using the auto level up and she's picked up Weapon Finesse (Mythic) and just now took Fencing Grace (Rapier). I'm using a +2 Rapier weapon on her (Mind Piercer) and she has +6 dex bonus.

-Weapon Finesse says it uses the dex bonus instead of str and sure enough her character screen damage went up by 6. Great.
-Fencing Grace also says it allows using the dex bonus instead of str if fighting with 1 hand and the other hand is empty or using a buckler. This seems like a duplicate pick?...

When I cleared her offhand weapon, her listed damage went up again by 3? The text of these does not sound like they should stack at all, although if they do not stack it is a very stupid auto level up selection to have her take a duplicate feat. That's potential bug #1.

Potential bug #2, Fencing Grace specifically says you can use a buckler. But as soon as I give her a buckler her listed damage goes down by 3. This neither matches the text that I can use a buckler nor is equal to my dex bonus.

Is this buggy or is there a mechanic I'm missing? Does an open offhand boost mainhand damage?

It seems to be adding 1.5 x Dex bonus just as if you used a weapon two handed and got 1.5 x Str bonus. Whether this is intentional I'm not sure.

Weapon Finesse lets you use Dex instead of Strength for your attack bonus. Not Damage. Fencing Grace lets you use dex for damage with the weapon you pick. Weapon Finesse is a prerequisite to take Fencing Grace. So not a duplicate pick. You'd have seen that if you were doing her levelup manually.

Fencing Grace does work fine with a buckler. Both my main character cavalier and Camillia use rapier/buckler just fine. You're probably seeing the benefit for wielding a one handed blade with two hands.

That's Weapon Finesse, Weapon Finesse (Mythic) is damage.

Okay, I was unaware you could get a 1.5x mod from using a rapier with 2h, so that explains the 3 damage I lose if equipping the buckler. But does sound like Finesse (Mythic) and Fencing Grace are duplicate picks.

Oh sorry. I missed the (Mythic) part. Yes mythic sounds like a duplicate feat for her. The mythic version lets you get dex instead of strength on every weapon, not just finesse ones. So weird pick for her.

But the game recommended I take Point Blank Shot for my horse, so I stopped listening to its choices. :D
