It's completely normal and ok! The only time I do not get much (if any) sediment is when I keg the beer and if I do not finish the keg before the next brew is ready, then I bottle the remaining beer using my "Last Straw" bottle filler.
As others have said, you have given the yeast some priming sugar to feed on and carbonate, this is a natural result. Plus if there is any hop sediment or break material that makes it into the bottle, it will sink.
Congrats on your brew! How did it turn out for you? Was it your first brew? What did you make?
