Several Twitter Tools issues — schedule, categories, and errors

Twitter Tools pulling my tweets correctly, but I’m running into some issues:

1) It will consistently schedule them to be posted on my blog after about four hours, instead of immediately.
2) It’s not setting the correct category for the tweets — no matter what category I choose, it always uses the same one (the wrong one)
3) When I try to delete a blog post that was created from a tweet, WordPress crashes with this error message:

Warning: Invalid argument supplied for foreach() in /home/equivoca/www/www/wp-content/plugins/social/lib/social/controller/broadcast.php on line 480
