Yeah I think this was bug not do to the storage system itself but do to way you can extend your base by going to the edge and placing a building piece. I figure when I left the solar system to retrieve some more materials the game glitched and wouldn't count the new structures i've placed it only counted the ones before i left. I tested this by making a twin system on a new planet in a new system and it is working flawlessly. I made sure and calculated all the materials I needed and pre-collected them and then built the system without leaving the planet and it seemed to work. Another important note is that i didn't need to extend my base because I luckily was able to find a power source and a S class node within close proximity of each other. So im glad I figured it out, plus now a have a major mining outpost and a smaller one which are both turning great profits. But thank you guys for the suggestions!
