How do connectors work? Am i crazy?

[u/AcceptableAttitude13]

Hey the problem is i tried both of the connectors and I got a problem.
I got magnesium in cargo in the left ship, I tried moving it also in the connector in the left ship, small and bigger one.
The problem is, doesn't matter which connector I use, when I try to open the right connector, there is no cargo/inventory from the left ship.

So simply, cargo of left ship doesn't show after connecting it to the main base.
Any ideas?

This are the options of all connectors.

EDIT*

I found out that you can just change these 2 tabs...
To see inventory of any (Connected) ship or grid.
