If the Stronghold Package and Structural Ergonomics are the last two items you are attempting to purchase from the Store (and you didn't purchase them when they randomly appeared with other pieces of equipment), they WILL NOT appear in the Store. This is a known issue and can no longer be fixed. However, if all of the other 30 pieces of equipment are owned, purchasing one of the MP DLC Pack - Collection Items packs will force the equipment items to appear as a substitution for the equipment listed in the pack.
For example, if you have all of the remaining 30 equipment items, and you purchase the Asari Adept Multiplayer Recruit Pack, already having the Commando Package will force either the Stronghold Package or the Structural Ergonomics piece of equipment to appear in the pack. Purchasing a second DLC pack after this (such as the Krogan Vanguard Multiplayer Recruit Pack) will then force the last remaining piece of missing equipment in the pack.
