How much did you tighten the BB guide? I've had frames with a similar issue, but it turned out I screwed the guide in too tight.
...
This was a different frame though, so this may not apply to the 1056.

I asked myself the same question :-) and afterwards also asked Wing. She replied that there are different batches of the CFR1056, and by mistake I received one with this specific "shape". I guess it is a variant intended for an bicycle OEM... Everything else islike shown on the drawings.

That reminds me of the first-gen FutureShock frames from Specialized. See for example https://www.specialized.com/be/en/roubaix-expert/p/115446?color=214966-115446
Although yours looks more "pointy" (like a fin) in that picture.
