In the screen shot shown, you are loading resources, not supplies. With the original WITP, the TF would not leave port until it was filled 100% when loading resources. This would cause the TF to stay in port for day and even months, especially for those ports that were slow in producing resources.
IIRC, one of the features for AE was that the CS TFs hauling resources would leave port once a certain load percentage was reached. I believe the theory is that, if there were plenty of resources, they TF would fully load. If there wasn't a lot of resources available to load, then the TF would load to a certain percentage and then head for it's destination.
Also, IIRC, a TF will only take a certain percentage of the resources available and will not take 100%. In other words, if there are only 1000 resources available, then TF will only load 80% of them, or 800 resources. However, I'm not completely sure about this or the percentage.
EDIT: p.s. - Amphib TF will only load to 80% of capacity.
