I added a material to my bottle model with the transmission set to 1 and roughness to 0.01, with the base color set to a brown-orange.
The color only appears in the center, and the edges just reflect the HDRI. When I look at the bottle in material preview the color is applied to the entire bottle.
However, when I apply the same material to a sphere, the color is on the entire sphere.
I'm also using the bevel, subdivision surface and smooth by angle modifiers, but deleting them didn't help.
