Guardian's Default eyebrows, the 'Triumphant Arches' was obtained in a cosmetic box, so now there are two copies of the same eyebrows

I somehow was able to get duplicate eyebrows on my Defender. I have 2 of the "Triumphant Arches".

I got a duplicate triumphant arches from a cosmetic box for the guardian, even tho they are the default option for the eyebrows

I got the Triumphant Arches eyebrows for Guardian from a cosmetic crate, but those are already the ones he has by default.

Guardian has the Triumphant Arches twice, and Falconer does not have it as an available cosmetic. Likely an error.
