Adding the ACE3 AGM-65s (single, dual, and triple variants) to helicopter.

[Tylertron1998]

Hi, I've spent the last few hours trying to go over and add the AGM65's to a helicopter, with very little success. I'm wondering why exactly I can't - the confusing part is, on the pylon settings, the AGM-65 singles are already there. But the double and triple racks seem impossible to add - I'm not sure what I'm doing wrong. Any advice?
