Nexus Clash

As a Nexus Champion, I took the new Field Supplies skill that is supposed to give me 20 extra inventory spaces. So today I was looking to take a factionmate's armour to fix, and it came up with a message about me not having space despite my inventory slots showing as 68/90. More than enough to deal with any armour, let alone an 11 weight chainmail shirt. It did allow me to take the chain mail shirt out of my faction locker so I was able to repair and return the armour, but I feel like the faction locker bit was unnecessary? If that is how it works then so be it, just seemed weird.
