This is actually a display bug, not a functional bug. You will find that there are indeed individual permissions for each rank, and you can set them differently.
The workaround is:
-set the permissions for a rank, then switch tabs (e.g., click on Fleet Uniforms, then click back again to Fleet Settings) to see the changes to the rank you just changed
-click on another rank, switch tabs and switch back to see this rank's permissions
-repeat for all
This is an annoying display issue. Bug report it!

Go into your Game Options, Key Binds settings. You can bind a key to open the Fleet window, and you can keep the Fleet window set to the Roster page.
