I am having a few errors with altium when it comes to the PCB part.

1st Overlap or too close???


I know this generally means that parts are too close but since I just dragged and dropped on to PCB I get this green colour straight away, could this be a design rule that's on?

2nd Compilation errors I get a lot of these errors which i dont know how to fix. I know the duplicate pins is regarding custom foot prints that ive made but not sure if i should just ignore this?

Also i get these "Temporary mash data" all the time. Does anyone know how to fix this?

Thanks for your help.
