You can only get the highest modification available at your rank.
If you are ranked Captain, you have access to M2 modification. This update changed the way things work. It allows you to save crystals by 'skipping' the previous modifications. My advice - next time ignore micro-upgrading on lower levels and start investing into the micro-upgrades once you reach the M3 equipment. There are only two options if you want next modification of Hornet in your garage; either purchase Hornet M2 or save for M3 modification.
