Can't attach cargo

I'm using the Destroyer v2.0 ship mod to play the game but the problem is I can't attach cargo to the ship in the hangar/loadout/add cargo. The ship shows that it has 5 internal cargo bays but I can't seem to find the 'add cargo' button.

Can't anybody please help me out?
Thank you.

Are you using this mod with Torn Stars? Because that is not a mod for Torn Stars, and won't work with it. Somebody more familiar with EoC might be able to help you out though..

Those internal bays are not used for pods of cargo, but instead are used for large systems like extra collider rings or internal magazines.

When you launch, I believe you can select one cargo pod to take with you at launch.
