The stats will be updated, but this sometimes takes awhile!!
Be patient [as it says in your sig!] [Nice one!]
Are you seeding all these uploads?
Ideally you need to concentrate on allowing your uploads to get completed rather than speed uploading multiple torrents.
This would allow you to seed the latest torrents leaving the others to those that have downloaded.
I do not know what your internet connection is but you are going to be hard pushed to service 50 + torrents in a couple of days.
