Can't purchase Mark 5 armor bundle

Just like the title says. I bought a good chunk of credits to get the Mark 6 and 5 armor bundles. I bought the Mark 6 bundle no problem, but when I went to buy the Mark 5 I got the credit screen that pops out when you don't have enough credits to make a purchase. Ive tried logging in and out of the game, and resetting my computer. I even tried topping off with a few extra credits and I still get the glitch. Is the bundle actually not 2,200?
