Component footprints have holes and connectors on each side regardless

Layout Footprints
1

I am new to KiCad, and PCB design in general. I am creating a simple PCB with 2 layers.

What I don’t understand is when I place a surface mount component on one side, connectors for the component are showing on both sides of the board . Also when adding a through-hole component I would expect the connectors for the component to be on one side only, but they are on each side.

For example, I have a surface-mount slide switch with its footprint, and a through-hole LED with its footprint, but the model appears like this. I was unable to embed two pictures showing each side, but see the switch terminals next to the LED, they shouldn’t be there as the switch is on the flip side. Likewise the LED terminals should be only on the flip side? Thanks in advance for any help.

Those are all through hole components. As the name implies the connections are through hole so will appear on both sides of the PCB.

a SMD component will only appear on one side and will not have any through hole collector on it.

For example, this is a SMD footprint for a random switch I found:

This is similar switch but with through hole:

Check what footprints you have assigned to the symbols.

Through hole footprints and SMD components can be flipped to either layer, but with through hole components the hole with be through both layers regardless of which layer its on.

@gmc Thanks for your reply. I need to check the footprints. Clearly something is wrong in that case.
