(I did this experiment: I change the "footprint" just now, & saved it in my local library, to match the "symbol" pins, then I re-associated that with the component. & then, I did get TWO pins right this time, and they were also connected OK. & now, the error was reduced to only one pin - VO)
So I think, I can see that you are right. I should edit the "symbol" rather than the "footprint"
I will also try this method, tomorrow or so,..
But thanks to all of you for your help , as now i know, what the problem basically is.
