So I am learning and there are a few things wrong here but with one I have no idea where to start even looking for help.
With the Strange Mirror Effect on the Bottom of the Chair? Its taking the shape of the cylinder and painting it above it?

Low Poly Mesh

High Poly Mesh

High Poly Mesh Less Clutter

I've tried swapping the vertex colors, even making it the same vertex color and i've brought the arm down slightly in hopes it would stop the echo or shadow effect.
I know there are some other errors here, around the cylinders joining the flat surface that need more geometry and the edge connecting to the seat which I might be able to fix with more edge loops, but with the mirror effect here above the cylinder I don't even know where to begin

Any suggestions where to look for a problem?
Thanks in advance!
