Why can't I commit changes to my submodules?

[Pipi Fakidomyth]

When I update my submodules, the option to commit is disabled. Maybe I'm not using submodules properly? Please have a look at the attatched image:

The file-level commit is disabled because you've already staged these changes (it's actually the same for all files which are staged). Because you've staged the changes, it's the top-level commit (toolbar or Ctrl-Shift-C) that commits staged changes. You can only commit individual files unrelated to the index when they're unstaged.
