*reads about hard cap on fleet size*
Can that stuff be edited via fiddling with game files? If not then I have another question.
Can I get a refund? I didn't buy this game to run tiny it's bitsy fleets. I always go big. D:
Considering how you can mod almost everything in the entire game to your liking (you can even re-activated old and now-unused features again, just like how it was with ammo), it's very likely that you can adjust this yourself somehow.
However, it sounded like it was some sort of UI-restriction, so it might be that the ships you have beyond the cap are not visible in all parts of the UI (the 'main' fleet window probably won't show them, but the old refit-list where you can just scroll up and down should still work for them).
