Error reading netlist in Pcbnew


So, am have created my schematic, assigned footprints to the components and generated the netlist…

When I come to read the netlist in Pcbnew, it doesn’t load all of them stating that it ‘cannot add new component due to missing footprint’ even though I have definatley associated a footprint to all of the components.

I would appreciate some assistance on this matter please.

Kind Regards,
