Help Naked Edges

Hi everyone,

Can you help me with repairing these naked edges? I created planar surfaces to close the sides and a surface from an extruded arc. For some reason these surfaces aren’t joining with the middle shape.

I am also confused why on one side some edges are good and some are naked despite mirroring the exact surfaces to the other side.

You are the best. Thank you.

So you think the points where not on the same plane?
