This was intentional behaviour. The idea was to put them near the edge of their range from the target, so that defenses would have a harder time reaching them. The problem is, sometimes their range is longer than their LOS, so they never attack the target.
Placing at the edge of their weapon range is a sensible option for low-HP units with long range, like merls and artillery, but everything else should put themselves within their LOS from the target.
