I have noticed that if I queue up multiple upgrades to logistics and then queue multiple ships (say, 5 capital ships) it will not begin building ANY until the amount of current logistics and captains zero out.

Example:
I have 4 capital ships. My research allows 4 capital ships and more then enough regular logistics.
I queue research for two upgrades to the capital ships captain amount, one from 4 to 6, and the second from 6 to 8.
I then queue 4 shiny new capital ships in my shipyard.
When constructions will not begin until both research projects are done!
After the first research is over I have now capacity for 6 ships, but -2 is displayed, at that point it should start building the two new ships I now have capacity.
If I cancel two ships from the queue it immediately starts construction, and then I can readd them to the queue. to ensure I have all 4 ships queued and that it is building the 2 it currently can. instead of waiting for the second research project (6 to 8 capacity) to finish.
