Capsule shop help

Hi... im trying to buy things in the capsule shop with euros + battle points but it keeps say cant purchase capsule (not enough euro) and i cant figure out why...

So it says currently for sidewinder 167/200 and i want to purchase 5 capsules for 5000 euros + 250 Battle points... I currently have 20,294 euros and 383 battle points yet it says not enough euro....

Any Help (already am high enough rank [staff SGT. 3rd class])

I'm not sure if im a complete idiot or not but any advice would help...

Thanks In Advance....
