Cargo Hold Bug on my map that I cant seem to fix

[JomarTaaca]

Hello, Ive been editing the Tree Tag Map.
And I made a (Normally) Human siege Engine into a Tank, I already got that to work.
But the problem is, the Tank can Load itself all over again, it can load itself to full and load into another tank, I cant seem to find how to fix this. And yes I am sort of a World Editor noob.

I just the tanks to be able to load units, but not load itself

But thanks for your help

Edit Stats - Transported Size of the tank to be greater than the transport capacity of the tank.
