+The DSN format was originally designed for autorouting; an autorouter doesn't +need to know the geometry of a hole, assuming copper annulus is always around +the hole. Thus old versions of the file format simply does not have a way +to describe holes. +
+Some software extended the format and use a hole directive that pcb-rnd +picks up - but if the file does not contain holes, pcb-rnd can't improvise them. +
+You can use query() to find offending padstacks and use propset() or +the padstack editor to install the holes.
