Pcb ic pins inorrectly connected

I’m new to KiCad, so please bear with me!!

I’ve setup my schematic that connects pins of a 40 pin Raspberry Pi2 to a 8x2 MCP3008 IC.

In the schematic several green wires cross each other although they are not connected - is this correct? Or, should there be little bumps where the wires cross schematically but do not cross physically?

When I generate the PCB I have a white wire on the right hand side of the MCP3008 that is incorrectly connecting all 8 pins to each other.

The pins are not connected in the schematic and so I don’t understand why they are connected in the PCB.

Anyone see this before?

Thanks.
